Как исправить error while request

The Internet is an everyday part of our lives, and most of us use it daily. And one of the common problems we encounter is An error occurred while processing your request issue on different browsers and apps.

The worst part is that the error message doesn’t divulge what’s actually causing it, making it all the more difficult to resolve things.

If you have been trying to find a solution, read the following sections for fixes that worked for users.

Why am I getting An error occurred while processing your request?

Several factors can cause this error message. Below are some of the potential causes:

• Server issue: When you encounter this error, it’s most likely that the application or website’s network is down. And there’s nothing you can do but wait until it gets fixed.
• Corrupt browser data: Corrupt browser cache or cookies can lead to this error, along with a few extensions. You need to clear these data and disable your extensions temporarily.
• Faulty certificate: Sometimes, you can encounter this error because your SSL certificate has expired. You need to delete the certificate and recreate it to solve the problem.

How do you fix An error has occurred while processing your request?

An error occurred while processing your request on Chrome

1. Try another browser

If your current web browser continues to give you a hard time with error messages, we recommend you try another one until you remediate the problem.

One tool that scores high marks in the stability department is Opera, thanks to the ultra-modern Chromium engine that it uses, which it shares with Google Chrome and Edge.

It is lightweight and can be significantly altered visually and functionally via extensions. If that isn’t enough, then maybe the built-in VPN and ad-blocker will convince you to give this browser a shot.

Opera

Enjoy a stable and error-free browsing experience with the help of this fantastic and ultra-lightweight web browser.

2. Delete your browser cache to fix

1. Launch Chrome, and press Ctrl + Shift + Delete to open the Clear browsing data window.
2. Select All time from the Time range dropdown menu.
3. Now, tick all the checkboxes here, and click on Clear data.

Users reported this error while trying to access certain websites, and according to them, the solution was to remove browsing cookies.

After clearing the cache, restart your browser and check if an error occurred while processing your request on Chrome is resolved.

If the problem persists, there might be an issue with the website itself, and the only thing you can do is contact the website administrator.

3. Delete the SSL certificate

This error can appear if your SSL certificate is expired, and one way to fix it is to delete the certificate and recreate it again.

Users reported that after deleting and recreating the security certificate, the issue was entirely resolved, so be sure to try that.

According to users, specific certificates will last only a year, so you’ll have to remove them manually and recreate them.

4. Try visiting a non-encrypted version of the website

Many websites use HTTPS protocol to encrypt their traffic and protect their users’ privacy.

Unfortunately, some websites might have problems with HTTPS protocol, so you might want to use unencrypted HTTP protocol instead.

To do that, look at your website’s address, and if it has https at the beginning, change it to HTTP and press Enter.

5. Disable the HTTPS Everywhere extension

As we already mentioned, the HTTPS protocol encrypts your data and protects your privacy, but not all websites support HTTPS.

To avoid this limitation, many users rely on third-party browser extensions such as HTTPS Everywhere.

This extension forces websites to use HTTPS protocol instead of HTTP, which can lead to problems.

Some websites don’t support HTTPS protocol, and by forcefully using this protocol, you can cause An error occurred while processing your request error to appear.

One of the simplest ways to fix this problem is to disable the HTTPS Everywhere extension for the website that gives you this problem.

Alternatively, you can remove the extension from the browser altogether, which would fix An error occurred while processing your request issue.

An error occurred while processing your request. Please try again later on OpenSea

The first thing you should do here is to wait for a while and let the backend team fix any issues with the platform. Then, if that doesn’t work, you may try clearing the browsing data.

Also, ensure that the NFT you add is part of a collection, though OpenSea should do that automatically.

If you are receiving the error when accessing or using your wallet, try removing and reconnecting it to the OpenSea account, and An error occurred while processing your request issue will be resolved.

An error occurred while processing your request on TikTok

When encountering An error occurred while processing your request message, your primary approach should be to check if TikTok’s services are down, though that’s rare. To do that, use DownDetector, or other similar platforms available.

Also, simply logging out of your account and signing back in is known to fix several problems. Besides, you can restart the device or reinstall the app if nothing else works.

An error occurred while processing your request on Steam

Although this error appears on certain websites, many Steam games use a web launcher to start, so it’s not uncommon to see this error while trying to start certain games on Steam.

Therefore, if you’re getting An error occurred while processing your request error while trying to start a game using the web launcher, you might want to try running the game directly from your Steam folder.

Users reported that they could circumvent this problem simply by using the game’s .exe file to start it directly.

An error occurred while processing your request on Xbox

The error is encountered when accessing the official Xbox website and is mainly limited to European users. Though there have been instances of other users coming across it.

To fix the error, the best solution would be to use effective VPN software to reroute your connection. If that doesn’t work, you may switch to the Xbox app while the backend team resolves the error.

An error occurred while processing your request. Reference #30

This is encountered while using the web version of a game and trying to log in via the Xbox account. When the game redirects you to the official Xbox website, the error appears after you enter the login credentials.

A simple fix would be to clear the browsing data or use another device. Also, it could be a browser-related issue, and switching to another practical browser, like Opera GX, which is developed for gaming and offers various customizations to boost the experience, would do the trick.

An error occurred while processing your request on Facebook

1. Log out and log back into your account

One of the most straightforward solutions you can try if you’re getting An error occurred while processing your request error on Facebook is to log out and log back in after a few seconds.

This is a simple solution, and it might not work for everyone, but you can still try it out.

2. Clear your phone’s browsing data

A few users reported that they cannot link their Facebook account with other third-party services due to this error, and one way to fix this problem is to go to your Facebook Mobile app and look for the Clear your phone’s browsing data option.

After clearing the browsing data, this error should be fixed, and linking to third-party applications should work without any problems.

Wait for the website administrator to fix this problem

Users reported An error occurred while processing your request reference 97 error while using Steam’s website. And according to them, it seems that this issue is related to Steam and not to their computer.

If you encounter this error on Steam, wait a couple of hours for the website administrator to fix it.

An error occurred while processing your request error can be problematic and prevent you from accessing your favorite websites. We hope you managed to fix this problem by using one of our solutions.

Also, if you are using a free VPN, the IP address might be marked as having suspicious activity. In this case, change it to a recommended VPN service.

If you’ve stumbled upon this post, it probably means that you’ve just tried to deploy your ASP.NET Core 1.x or 2.x web application to a production Windows Server 2012 or 2013 with IIS 8 (or later). Before doing that, if you’ve read the official MS guidelines on publishing .NET Core web apps on Windows/IIS, you’ve most likely equipped your server with the .NET Core Windows Server Hosting bundle, which installs the .NET Core Runtime, .NET Core Library & the ASP.NET Core Module and also creates the reverse-proxy between IIS and the Kestrel server which is required to host .NET Core web apps.

All good, right? Except that you’re facing the following error right after publishing your app:

An error occurred while processing your request.

Request ID: 0HL919KOB00BC:00000001

Development Mode

Swapping to Development environment will display more detailed information about the error that occurred.

Development environment should not be enabled in deployed applications, as it can result in sensitive information from exceptions being displayed to end users. For local debugging, development environment can be enabled by setting the ASPNETCORE_ENVIRONMENT environment variable to Development, and restarting the application.

Don’t worry, that’s quite a common scenario when publishing a .NET Core web application for the first time: despite the official documentation reassuring tone, the deployment task isn’t always easy, as the required reverse-proxy mechanism between IIS and Kestrel undeniably adds an additional level of complexity to the already-present potential issues (mostly depending on the server machine state) that can prevent it from going well.

Luckily enough, there are a lot of things we can do to diagnose the most common problems. Here are the most relevant ones:

• Read the browser’s output messages, optionally setting the
  ASPNETCORE_ENVIRONMENT  variable to
  Development  to print out the stack trace and/or the exception(s) details.
• Examine the Event Viewer’s application log.
• Enable the ASP.NET Core module stdout logging feature.
• Try to reproduce the error(s) on Kestrel

In this post we’ll take care of the first one of them, learning how we can set the ASPNETCORE_ENVIRONMENT environment variable to Development, being it the first time we should learn to do when dealing with .NET Core web apps within IIS.

The ASPNETCORE_ENVIRONMENT variable

As clearly explained in this official introduction to .NET Core environment fundamentals, ASP.NET Core provides support for controlling app behavior across multiple environments, such as development, staging, and production. Environment variables are used to indicate the runtime environment, allowing the app to be configured for that environment.

In our specific scenario, the ASPNETCORE_ENVIRONMENT variable is our buddy, as it’s being used to describe the environment the application is currently running in. This variable can be set to any value you like, but three values are used by convention, corresponding to the three environment defined above: Development, Staging, and Production. The default environment setting will be detected programmatically from within your application and can be overridden by setting up this variable accordingly.

We can do that in two ways:

• On server-level scope, by actually setting a system-wide environment variable, using the Control Panel > System > Advanced Settings > Environment Variables GUI interface.
  On app-level scope, by altering our web app’s Web.config file and override that value there.

It goes without saying that the latter method is generally preferable, as it will only change that behaviour for our web app, without affecting the whole web server.

(Re)introducing The Web.config file

… Hey, wait a minute! Did we just say «our web app’s Web.config file»? What happened to the «no Web.config file required» tagline which was repeatedly spoken and sweared upon on almost all .NET Core webinars, demos, promos, hands-ons and highlights?

As a matter of fact, that’s still true, at least for the application settings part — which is now stored in the appsettings.json files. Sadly, that’s not the case for IIS, as it’s still require a Web.config file whenever we’re going to host our app using it. Or, to better say it: the
<system.webServer>  section of Web.config is always required to configure most IIS features, regardless of the server-side and client-side technologies we’ve been using — including those that apply to a reverse proxy configuration, such the one that we need to implement. It’s important to understand here that it’s not something strictly related to .NET Core, as it’s also true for PHP web apps, Phyton web apps and basically everything else that can be configured to run within IIS.

To better understand this, it can be useful to take a close look at the following lines from the MS official docs on .NET Core publishing with IIS:

[…] .NET Core apps are hosted via a reverse-proxy between IIS and the Kestrel server. In order to create the reverse-proxy, the web.config file must be present at the content root path (typically the app base path) of the deployed application, which is the website physical path provided to IIS. Sensitive files exist on the app’s physical path, including subfolders, such as my_application.runtimeconfig.json, my_application.xml (XML Documentation comments), and my_application.deps.json. The web.config file is required to create the reverse proxy to Kestrel, which prevents IIS from serving these and other sensitive files. Therefore, it’s important that the web.config file isn’t accidently renamed or removed from the deployment. […]

And also, later on:

[…] IIS configuration is still influenced by the <system.webServer> section of web.config for those IIS features that apply to a reverse proxy configuration. For example, you may have IIS configured at the system level to use dynamic compression, but you could disable that setting for an app with the <urlCompression> element in the app’s web.config file. For more information, see the configuration reference for <system.webServer>, ASP.NET Core Module Configuration Reference and Using IIS Modules with ASP.NET Core. If you need to set environment variables for individual apps running in isolated Application Pools (supported on IIS 10.0+), see the AppCmd.exe command section of the Environment Variables <environmentVariables> topic in the IIS reference documentation. […]

That said, let’s move on.

If the Web.config file is not present upon the application first run, it will be auto-generated in the root-level folder with the default settings that will best suit the application. That’s a typical example:

Here’s how we can tweak it to set-up the ASPNETCORE_ENVIRONMENT environment variable (updated lines are highlighted):

IMPORTANT: Don’t forget to replace the 
OurWebApp.dll  sample with your actual DLL file!

If we do that right after hitting an IIS error and then reload the affected URL, we should get some detailed info regarding our error who will most likely help us to understand what’s going on.

The «missing Node.js» scenario

The only thing we have to keep in mind is that switching to Development might also require Node.js — together with their relevant NPM modules — to be installed in production server as well: such requirement would most likely raise if we did use some switches — such as
dev.IsDevelopment()  — within our code to conditionally load NPM dependances in development mode.

If that’s the case, the first error you’ll receive would be the «failed to start Node process» one, just like in the screenshot below:

The above error is caused by the Webpack Dev Middleware, which was loaded inside a
env.IsDevelopment()  conditional block. If we don’t want to install Node.js in production, we can choose between reworking these middlewares loading strategies or (temporarily) excluding them.

Regardless of what we’ll pick, a thing is for certain: now we can properly address these kind of issues without getting an(other) headache!

IMPORTANT: Be sure to put that value back to
Production  once the issue has been fixed! Exposing these error details will leak potentially dangerous info regarding your web server configuration settings, thus opening it to harmful attacks. To get a better idea of that, just take a look to the above screenshot to see how many info could have been retrieved from these few lines if we hadn’t uglyfied most of them: the PATH environment variable content could show a lot of info regarding your server, such as installed software, version numbers, system folders and so on.
