I ask your help because my Raspberry PI4 Wifi network connection is unstable and I frequently lose the connection to Octoprint PC interface (http://octopi.local/#control).
However when i'm connected, my gcode downloads well and my 3D print continue to the completed end (even if I lose the PC to octoprint connection during printing).
So my only problem it's i can't to have a stable connection from my PC to http: //octopi.local/#control.
To resolve that, My CR10S pro still on, I need to turn off Raspberry power and disconnect serial cable to the printer. Then I power on supply of the raspberry and I reconnect the serial cable to the printer and I can reconnect to the interface http: //octopi.local/#control
To resolve that I tried to change several time serial cable / Closer the rasberry to my wifi box / Upgrade all software / Always Edit the octopi-wpa-supplicant.txt file with NotePad++
I'm not a specialist but my log file has line like this:
