network error after starting the app

[Solarbytes]

I got to the point where I start the app, and although it says it is running, nothing changes in the interface. I can't see any dashboards.

In the logs, I see hte following error:
Error: network Error : dial tcp: lookup core-mosquitto on 127.0.0.11:53: no such host

I am not sure if this explains why nothing is happening or whether I am missing some steps in the configuration.

Im having similar problem.
Log shows following:
2023/07/08 09:10:31 INFO: Found SunGrow 2 devices
Error: network Error : dial tcp: lookup username on 127.0.0.11:53: no such host
Usage:

Aliases:

Examples:
GoSungrow mqtt run

It seems it tries to resolve username I have given in mqtt_user field.
