Error while attempting DP-602 and DP-603 Applied Skills

Hello All, since Saturday I have been receiving the following error while attempting DP-602: Implement a data warehouse in Microsoft Fabric and DP-603: Implement Real-time Intelligence in Microsoft Fabric. Today also when I tried to attempt, I received an error.  Can someone help me resolve this issue? I had good internet connectivity in spite of that, I couldn't attempt the Applied Skills. I even refreshed the browser, restarted/rebooted the VM but nothing worked. 

Please find the screenshot of the errors:

This was today

This is the error on Saturday.

Requesting you to kindly suggest a work around this problem.

Regards,

Manasi.
