Stuck in "Attempting to reconnect MQTT Broker..." loop about ring-mqtt HOT 2 CLOSED

The most likely issue is the attempted use of MQTTHOST=localhost when you're running both mosquitto and ring-mqtt in separate containers. If you are not using host network mode within Docker then you can't just use "localhost" to connect between Docker containers. With the current setup effectively ring-mqtt is attempting to connect to an MQTT broker within it's own container.

So you'll either need to change to using the IP address/hostname of the docker host itself instead of using localhost, or you'll need to add the appropriate "network_mode" to your docker compose. At least that's my guess based on what you've provided to this point.

Good catch! I had originally setup the container in network_mode = "host" but removed when I realized it didn't need any incoming networking. Changing MQTTHOST to the IP worked. Thanks!
