I upgraded my mqtt server from mosquitto 1.6.x to 2.0 and HA started to disconnect from the mqtt server every 5-6 minutes or so. The mqtt sever logs read as:
1672087211: Client <ha_id> has exceeded timeout, disconnecting.
HA logs are not very informative either:
No ACK from MQTT server in 10 seconds
There is a bug in HA addons page Mosquitto 5.1.1 is broken. · Issue #1887 · home-assistant/addons · GitHub with a similar error, but I have idea what mosquito 5.1.1 means, as the latest version is 2.0.15 (Download | Eclipse Mosquitto)
Has anyone had this problem? All my other services have no problem connecting to mosquitto 2.0
