Server Error in '/' Application. Runtime Error

Question

Whenever I try to visit "https://developer.microsoft.com/en-us/microsoft-365/dev-program" . I get the Server Error in '/' Application. Runtime Error. I have written the whole error below. Please help me to fix this.

Server Error in '/' Application.

---

Runtime Error:

**Description:**An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File --><br> <br> <configuration><br> <system.web><br> <customErrors mode="Off"/><br> </system.web><br> </configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File --><br><br><configuration><br> <system.web><br> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/><br> </system.web><br></configuration><br><br>***Moved from Microsoft Edge / Website issues / Windows 11***

Hi Rahul,

Thank you for posting in Microsoft Community.

I apologize for the inconvenience you are experiencing. The error message you are seeing is related to the website's server, and it seems to be a configuration issue. As a customer support agent, I do not have access to the website's server to fix the issue. However, we can perform basic troubleshooting steps to see if it will address the issue. It not, we can point you to the right experts that handle advance server related cases like this one.

I'd like to ask few questions from you to provide with the best resolution possible.

1. What browser are you using? Are you able to access any other website aside from the ones you're trying to access?
2. Are you using a VPN, firewall, 3rd party antivirus software, or probably connected to a domain network perhaps?
3. Did the issue persists when you try to use a different browser?
4. Can you try accessing the site in your phone and see if the issue persists?

While waiting for your confirmation, here's some steps you can try to see if it will address the situation.

1. Clear your browser's cache and cookies and try accessing the website again.
2. Try accessing the website using a different browser or device.
3. Try using an InPrivate or Incognito browser to see if the issue persists.
4. Wait for some time and try accessing the website again later.
5. Use a different connection.
6. Turn off VPN connection, Firewall, 3rd party antivirus and try again. these could have blocked you from accessing the site.
7. Try updating or reinstalling your browser.

If issue still persists, we highly recommend you posting to our dedicated experts in **** Microsoft Q&A to get exactly the information you need. They are the experts in this type of concern.

Hope I contribute to your concern.

Regards,
