Octoprint tells me: offline after error - Printer keeps requesting line again and again; communication stuck

On same positioin ( line 297268) the print is stopping and octoprint (Version 1.9) reports a communication stuck error. Firmware of my SV06 Plus is stock.
How can i handle this topic best?

either please upload the gcode file or post on the octoprint forums, preferably both, but might be able to advise it the gcode is uploaded
