Hello everyone,
I am running several mesh networks using ChirpStack OS. Randomly, the mesh system refuses to process downlinks, and the following error appears in the logs: 'Operation cannot be accomplished in current state'. I suspect this might be an issue related to the ZeroMQ protocol.
Restarting the mqtt-forward-mesh services resolves the issue, and everything starts working normally again. While I could simply set up a cron job to restart these services every hour, I would appreciate it if anyone could suggest a more elegant and permanent solution.
chirpstack-gateway-mesh --version
chirpstack-gateway-mesh 4.1.3
chirpstack-mqtt-forwarder --version
chirpstack-mqtt-forwarder 4.5.1
Just rebooted the gateway:

Thank you in advance.
I noticed that other people are experiencing similar issues. Apologies, but I was still using the old forum.
Could you please update your question with the version numbers?
Done. Tnx. Luca
