Unexpected error fetching DWD Weather Coordinator

[HomeAssistant310]

Hi,

first of all, thanks for this awesome integration!
However, after going through my logs because of another issue, I noticed that the DWD integration is causing some errors while trying to fetch data.

Yesterday there was a log entry about fetching data taking long, but nothing specific, thus I wanted to monitor the issue first.

Today I go the error below, which might be related:

The above exception was the direct cause of the following exception:

Hope this is of any assistance in making that integration even better!

Edit:
The other error just came up again:
