'Connection reset by peer' when sending a message

[freetomik]

Hello, I am getting ConnectionResetError every time the test-messages.py script sends a message.

Firefox prints in console:

Firefox can’t establish a connection to the server at ws://127.0.0.1:3000/mqtt. mqttws31.js:977:17
Host: 127.0.0.1, Port: 3000, Path: /mqtt TLS: false index.html:53:13 

Any help appreciated. I use mqtt-server.py as a broker.

This is a hbmqtt issue. A lot of Home Assistant users are seeing the same warning (e.g., home-assistant/core#20613).

hbmqtt support is no longer available as hbmqtt is in maintenance mode.

The recommendation is to use mosquitto.
