OK, that produced some interesting results. For your first suggestion, my
broker computer is running Hass.io (Home Assistant), which doesn't have the
ss command. I'll keep digging there to see if there's another way to
double check that the port is open, but the log seems to indicate it's
listening on 1883.
I installed mosquitto-clients on a raspberry pi that I'm not using for
Weewx or my broker. So far everything I try there results in the same
connection refused error. I've tried both as anonymous and as a user.
Here's an example of an attempt:
pi@piopolis:~ $ mosquitto_sub -h 192.168.1.35 -t test -u homeassistant -P
reallylongpassword
Error: Connection refused
Checking the log on the broker, I see no evidence of the attempt, which
would point to the port not actually being open. But then I try to connect
from my windows machine using MQTT Explorer and everything works. I can
publish messages and see them pop up on my broker machine. The log looks
normal.
