Connection refused usually means the other side literally not listening on
that port. You might want to check that 192.168.1.35 is listening on port
1883. That should be the ip address of your MQTT broker, not the ip
address of the weewx system that's trying to connect to it.
Here's me checking my MQTT server pi
pi@pi3:~ $ sudo ss -tupl|grep 1883
tcp LISTEN 0 100 0.0.0.0:1883
0.0.0.0:* users:(("mosquitto",pid=607,fd=5))
tcp LISTEN 0 100 [::]:1883
[::]:* users:(("mosquitto",pid=607,fd=6))
...and checking that process 607 is the MQTT server...
pi@pi3:~ $ ps -aux|grep 607
mosquit+ 607 0.0 0.5 8924 5128 ? Ss Jan12 7:49
/usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
Quick test with mosquitto is to get on a client computer and run:
mosquitto_sub -h 192.168.1.35 -t testingmqtt
And in another window send a message to that topic:
mosquitto_pub -h 192.168.35 -t testingmqtt -m hellothere
(and the first window that's subscribing should display the 'hellothere'
message the other window sent to the broker)
