Repetier Server 1.0.4 on Raspberry Pi 3B+ when trying to connect to Ultratronics Board with Marlin 2.0 Firmware.
Note : this firmware works since more than 4 years without any problem.
After a crash of the Pi (the printer has disappeared switched to "unknown") due to a power failure.
The printer setup has been recreated.
Impossible to connect to the printer, message in console :

I have tried dozens of different serial port configurations > Can't connect
Upgraded to Repetier Server 1.4.1 > Same issue
Re-uploaded the Firmware (no change in the firmware) > connection is OK
Turn OFF Printer, then Turn ON > Impossible to connect
Re-uploaded the Firmware > connection is OK
Turn OFF Printer, then Turn ON > Impossible to connect
Any idea or things to test ??
Thanks
