What is the problem?
Since I change from a rpi 2 B+ to a rpi 3 B+ the connection stop during the printing session.
I do not have access on browser and via ssh, the print is not affected.
I had format my SD samsung Evo 32Go and put a fresh install for the new rpi 3 B+
The rpi 3 B+ is conncted to the lan on Wifi 5G
I never have had this problem with my rpi 2+, maybe I should pass to regular 2.4ghz wifi. ?!
What did you already try to solve it?
It is now the second time it occures and my print still in progress, so I had do nothing yet.
Logs (syslog, dmesg, ... no logs, no support)
I will edit this post later if I can to post the logs. For now my print still running and can not restart the raspberry until it's finish.
Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)
rpi 3+ connected on Wifi 5Ghz
When the problem occured, the rpi disappear from the lan client list.
