Message deCONZ[nnn]: "No carrier"

Google translator :slight_smile:

Installation of a Conbee II with firmware 26660700, version 2.14.01 / 6.2.2022 on Raspberry PI4 - bullseye.

Phoscon-GW runs perfectly, I can switch lights with deCONZ as well as with iobroker, but for some time now I’ve been getting the message mentioned in the subject every 10 seconds.
Unfortunately, I cannot determine since when the message has been appearing, as the logs are regularly deleted.

/usr/bin/deCONZ -platform minimal --dbg-info=2 --dbg-error=2 > debug.txt
libpng warning: iCCP: known incorrect sRGB profile

What can be the reason?
