What is the problem?
Started getting 505 Internal Server Error when connecting to Octopi.
Everything was fine a week ago and I still have prints on the bed I haven't had time to remove yet.
What did you already try to solve it?
Tried looking through the logs but can't work out the root cause of the error. Errors show up but are all Greek to me.
Tried SSH and restarting the server but get the same result.
Have you tried running in safe mode?
Yes, exactly the same result
Did running in safe mode solve the problem?
Nope
