Same as title, I wanted to know whether everyone is facing this issue or not. I tried from my friend's account, used VPN, changed browsers, cleared cookies but nothing helped. The practice section works fine but theory section does not load and gives a timeout with error: What happened?

The origin web server timed out responding to this request.

The likely cause is an overloaded background task, database or application, stressing the resources on the host web server.

@MikeMirzayanov It would be grateful if you can look into this issue
