Hi guys, I'm having a Communication error with the hotend around 190~200C and I appreciate your help.

I have an Anet a8 Plus with SKR 1.l4 turbo and BLtouch. This error started yesterday for no reason.

The printer suddenly stops sending temperature reports:

Normally they come about every 2 seconds. There is a time gap of about 1 1/2 minute between the last report and the error message. In this situation, is there any specific message on the printer's display?

I don't have a display. All I use is the octoprint
