Having problems getting Octoprint to connect with the printer. When I hit connect, the printer restarts, goes through Sorting Files, to main Information screen but Octoprint says it can't connect. Log shows:

Connection closed, closing down monitor

Any ideas? Windows 10, RPi 3+B, USB from RPi to printer, direct connection to my router port. .017 version of Octoprint. Thanks
What did you already try to solve it?
Changed router ports. Octoprint currently set at Auto Baud Rate Detect because my other option "/dev/ttyACM1" didn't work either.
