MQTT logs, errors - Githubissues

Operating environment/Installation (Hass.io/Docker/pip/etc.):

Windows 10 x64, using pip.

ESP (ESP32/ESP8266, Board/Sonoff):

ESP8266, NodeMCU v2

Affected component:

MQTT

Description of problem:

The problem based on the MQTT component. If I configure it using wrong broker URL (like 'asdf') it will accept without warning and it will run and try to report to it. Of course, it won't be reported but I can't get any logs about the failed connection.

Also tried this setup with the port number too. Changed the default 1883 number to something like '11883' run it, but the result was the same as I mentioned above.

The last thing I checked was the credentials. I disabled anonymous reporting and then tried to use wrong credentials (username and password). The compile was successful, initial setup too, but never reported and I never got any errors or logs that something was wrong configured.

Additional information and things you've tried:

I'm using DuckDNS to access my broker from a different place. I connected to the broker with other clients, so I know it is accessible from outside.
