Can't connect to printer - Post upgrade

What is the problem?

I've recently updated to 1.7.0rc2, every thing was fine after the initial reboot, however after installing a new Plugin (Plotly Temp Graph) and restarting, I was greeted with the following error

State: Offline after error
No more candidates to test, and no working port/baudrate combination detected.

This is what I've done so far

  1. Disabled the plugin, with no affect
  2. Booted into safe mode with no affect
  3. Tested the printer with the same cable on another pc, I can see the device appearing (not tested printing).
  4. Connected to octopi on the cli, the following is appearing in the journal.

Did running in safe mode solve the problem?

no

Is your printer connected using USB or via the GPIO pins of the Pi? Is /dev/ttyACM0 the usual port you would connect to the printer using?

I'm using USB to connect to the printer.
Under the connection port, I had it as Auto, I've updated it to point explicitly to /dev/ttyACM0, and I have the same issue.

Morning all

Is there any more information that I could provide?

Okay, I seem to have fixed it.

I don't remember if previously it was set to auto-detect the interface/baud rate.

However after manually setting it (baud of 115200) it connects without issues.
