Yes Ewald that's exactly what Octoprint delivers! a message telling me to restart the server because it had stopped.
There is a half-finished print on the printer, bed & nozzle are heated and the printer is waiting for print commands.
After restarting and reprinting it sometimes works, but mostly the same error.
All this after Update to 1.10.3.
previously it ran without errors
