Description

Hello,
I have 2 Lilygo Supreme devices. When I configure WiFi and enable MQTT, the devices randomly reboots.
One device is very close to AP one more far away and based on logs they do not drop connection to wifi.
But I found this in the middle of the serial log, it seems it is randomly loosing connection and reconnects:
INFO | 08:08:44 863 [Router] MQTT not connected, queueing packet

ERROR | 08:08:44 863 [RadioIf] ignoring received packet due to error=-7

DEBUG | 08:08:44 863 [RadioIf] Packet received (noise?) : 170ms

DEBUG | 08:08:47 867 [mqtt] Publishing enqueued MQTT message

However eventually I get a panic due to buffer being full, see log.
It seems this situation is not handled well.

Can I avoid this somehow and keep MQTT? If I connect it to Linux meshtasticd and maybe process MQTT there somehow?
Or is it public server issue?

Relevant log output
