Printer won't disconnect from Octoprint

What is the problem?

Octoprint will not stay disconnected. I do not have "Auto-connect on server startup" checked but it does so regardless. When I click disconnect in the Connection panel it disconnects and immediately reconnects.

What did you already try to solve it?

Not sure where to begin for this. Tried running in safe mode, and spot checking the logs, but I don't know what I'm looking for exactly.

Have you tried running in safe mode?


Did running in safe mode solve the problem?

Many 3rd party apps will try and connect to the printer automatically themselves. I know OctoDash and OctoScreen do, OctoApp (android) does as well. Do you have 3rd party apps configured?

You were 100% right. OctoScreen was the culprit in my case. Thank you very much
