What is the problem?
When I press "connect" in the Octoprint web page, it says "connecting" for a while and then returns to "offline."
What did you already try to solve it?
- Lowering baud rate
- Reboot in safe mode
- Disable automatic firmware detection
- Disable blacklist
- Restart octoprint
- Restart web page
- A fair amount of googling

Note: I had Octoprint running fine on basically the same setup before, but had wifi issues with my Orange Pi Zero. I have replaced with another OP Zero and re-installed.
