Hello there,

If you are experiencing issues with the web enrollment page not loading, follow these steps to troubleshoot the problem:

Check network connectivity: Ensure that the server hosting the web enrollment page has a working network connection. Verify that the server can access the internet and that the client attempting to access the page is also connected to the network.

Verify the web server's availability: Confirm that the web server hosting the enrollment page is up and running. Check if the web server service is running and if there are any error messages or warnings in the server's event logs.

Clear browser cache: Clear your browser's cache and cookies to eliminate any potential caching issues. Sometimes outdated or corrupted cache files can interfere with the loading of web pages.

Try a different browser: Attempt to access the web enrollment page using a different web browser to see if the issue is specific to a particular browser. This can help determine if the problem lies with the browser configuration.

When I go to this url, the page responds by asking for login credentials. It is only after login credentials are entered that it goes to the message that the webpage cannot be found. THis happens from multiple computers, for multiple users, and from multiple browsers.
