Trying a restart to see if it solves the problem…

Restart got it working :slight_smile:

I can confirm that I’m facing the same… and a restart fixes the issue, but also can error again after a couple of restarts later.

6

Facing a similar (?) problem. Running 0.39.1 on Unbuntu (virtualenv) with a local Mosquitto MQTT server. HA logging says “reconnected to the MQTT server” every 10 minutes.

7

Also dealing with same issue. My log is near identical to OP. Only appeared after recent update to 0.39. Deleted the mosquitto.db file and it seems to be working OK for now.

8

Can you tell me where the mosquitto.db resides, I can’t seem to find it :stuck_out_tongue:

9

I took a look in the mosquitto.conf file located in /etc/mosquitto. It pointed me to /var/lib/mosquitto/

TY, just have to wait and see if it cure the problem :slight_smile:
