Error 1101 when fetching text with web compone

I use three web Components to fetch xml‘s.
two of them work, but one does not.
Now for the interesting part:
It loads, when using the companion, but not after compiling and installing.
The link itself works, as the problematic document does load on the devices browser. Any Ideas how to fix that?

Some url will expect to open in web viewer, such case also you will get this 1101 error. Better search :mag: in community
