MQTT errors: Belchertown connects repeatedly then errors AMQJs0008I socket closed

[bkcorwin]

Hello, Trying to debug my mqtt websockets configuration with the belchertown skin. I have mqtt setup and websockets. Both ports are open and listening. I can subscribe to the weather topic from the command line and I see data streaming in.

However, when belchertown connects to the server i get repeated errors that say

MQTT: MQTT Connected. Subscribing
MQTT: 2022-09-18T20:40:50+01:00: mqtt Connection Lost: AMQJS0008I Socket Closed.

This repeats rapidly and forever. Note the pi/raspberry user is actually correct and that was the user i setup when I did the mqtt passwd configuration

my weewx.conf belchertown config looks like

[[Belchertown]]
        skin = Belchertown
        HTML_ROOT = public_html/belchertown
        [[[Extras]]]
            mqtt_websockets_enabled = 1
            mqtt_websockets_host = 192.168.1.99
            mqtt_websockets_port = 9001
            mqtt_websockets_username = pi
            mqtt_websockets_password = raspberry
            mqtt_websockets_ssl = 0
            mqtt_websockets_topc = weather/loop

    [[MQTT]]
        server_url = mqtt://pi:[email protected]:1883/
        topic = weather
        unit_system = US
        binding = archive, loop
        aggregation = aggregate

myconfig.conf reads

persistence false

allow_anonymous true
password_file /etc/mosquitto/passwd

acl_file /etc/mosquitto/acl

# mqtt
listener 1883
protocol mqtt

# websockets 
listener 9001
protocol websockets

What would cause the connection to keep failing like this?

Thanks

I note now that when I verify that the port is being listened to, I only see an ipv6 entry for websockets.

tcp6 0 0 :::9001 :::* LISTEN 498/mosquitto

whereas on port 1883

tcp        0      0 0.0.0.0:1883            0.0.0.0:*               LISTEN      498/mosquitto       
tcp6       0      0 :::1883                 :::*                    LISTEN      498/mosquitto   

Perhaps this is the issue?

In your myconfig.conf add this and try.

socket_domain ipv4

for your weewx.conf I would change the host for MQTT to be localhost if mosquito is on the same host/device as weewx. also, on your skin config, since you are allowing anonymous access, you don't need to put in the user/password for the websocket, try commenting them out to see if that helps.

Also, seeing mosquito listening "only" on IPv6 when doing ss or netstat as :::9001 means that it's also listening on IPv4 as well.
