My Django website suddenly stopped working and I don't know how to go about fixing it. It has been working fine for weeks now and earlier on today but stopped a few hours ago. Sometimes I get a "Something Went Wrong :-(" screen with this error code/message: Error code: 504-loadbalancer

The site keeps loading. I have tried reloading the site and disabling and reenabling the site from the web app. My usage is at 27%. I checked the server error logs and there isn't anything.

The only thing is from the server.log:

Same, some host problems maybe… Just wait…

It looks like we found the problem and it should work now. Sorry for that.

Thank you! It's back up now.

Great, thanks for confirming!
