Answer 1

Hello

Thank you for posting in Q&A forum.

Here are a few steps you can try to troubleshoot the issue:

1. Ensure that your server's network settings haven't changed. Verify that the DNS settings are correct, and that the server can resolve domain names.
2. Check if the Windows Firewall or any other firewall is blocking access to the sites. You might need to create rules to allow traffic to and from the sites.
3. Make sure the browser settings haven't been altered. Clear the browser cache and cookies and try accessing the sites again.
4. If the sites use HTTPS, ensure that the SSL/TLS settings are correctly configured in IIS. Sometimes, disabling certain protocols like TLS 1.3 can resolve issues.
5. If your server is part of a domain, check the Group Policy settings. Ensure that there are no policies blocking access to the sites.
6. Check the Event Viewer for any errors or warnings that might give you more information about the issue.

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.
