Comment 3 for bug 1968797

I have the same problem.
I just tried to remove the applet from the dock to test if it behaves the same and it did.

debian 11
mate desktop

This seems to be the main problem why the applet does not work:
 while downloading current conditions data:
https://weather-ydn-yql.media.yahoo.com/forecastrss?location=GMXX6175&format=xml&u=c -> Couldn't download file 'https://weather-ydn-yql.media.yahoo.com/forecastrss?location=GMXX6175&format=xml&u=c' (Couldn't resolve host name)

The URL is not working because the DNS is not working:
