Cannot autodetect Prusa mini+ printer after firmware update to 5.1.0

[gald33]

Octoprint via octo4a cannot autodetect my Prusa mini+ printer after firmware update to 5.1.0. The server does load fine but does not detect the printer. In the phone app UI itself it appears that the printer is connected. Is it a known issue? What info should I provide to locate the problem?

Do you know what method you typically use to connect to the printer? Is it a serial cable or are you doing it over the network? I am seeing here in the changelog that they did a bunch of changes to the network protocol to speed it up.

Have you updated to the later 5.1.2 or 6.0 firmware? Or has an updated Octoprint / Octo4a recently helped your system?
