UNSOLVED MMM-OpenWeatherMapForecast does not receive data from the Internet

[Kostosso]

Good afternoon,

My module MMM-OpenWeatherMapForecast does not receive data from the Internet.
I installed MM on My Home Server in Docker. I used the karsten13/magicmirror image. Everything is set up and running great. In the default configuration, all modules worked except for the weather.
I did not dwell on this, but installed my own configuration that had previously worked on Raspberry.
All modules, including Google calendars, started up fine, but … But the weather forecast module does not work again.
I checked that from the mm container the ping openweathermap.org
command works fine.
However, the mm logs contain the following entries:

[OpenWeatherMapForecast] **ERROR** Error: socket hang up

There are no more errors in the logs.

Help me please. What is this error and how can it be removed?

Thanks a lot in advance!
