Why does a website keep loading indefinitely in Microsoft Edge while other websites work normally?

I am experiencing an issue where a Moroccan education portal keeps loading indefinitely in Microsoft Edge, while other websites open normally without any problems.So far, I have tried the following:

  • Refreshing the page
  • Opening the website in In Private mode
  • Clearing cache and cookies
  • Restarting Microsoft Edge
  • Restarting the computer
  • Checking my internet connection

The issue only affects this specific website. Other websites load correctly in the same browser.

What else should I check to determine whether the problem is caused by Microsoft Edge, DNS, cached data, or the website itself?

Any troubleshooting suggestions would be appreciated.
