Had a working Octoprint server with my Ender 3 Pro. Upgraded to BLTouch and started updating Marlin 2.1.x Bugfix and now Octoprint will not connect to printer
What is the problem?

No answer from the printer within the connection timeout, trying another hello
Send: N0 M110 N0125
There was a timeout while trying to connect to the printer
Changing monitoring state from "Connecting" to "Offline"
Connection closed, closing down monitor
What did you already try to solve it?
Verified connection/cable with Pronterface. Rebooted Octoprint. Tried changing baudrate in Marlin (reduce). Tried disconnecting camera (in case it was drawing too much USB power).
Have you tried running in safe mode?
YES

Did running in safe mode solve the problem?
Yes
Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

I'm guessing the next debug steps will be to undo all plugins and reinstall 1 at a time to see what is causing failure.
