Bridge HTTP-API not working on Android but on Windows

Hi all.
I have connected 3 Nukis with my Bridge.
From my Windows PC I can reach the Bridge and can perform Actions to the Locks by URL from Chrome, Firefox…
If doing that from my Android Device (Galaxy S22Ultra) I get an ERR_ADRESS_UNREACHABLE

I used the Search and Google but cannot find any similar Topics.

Can anybody help in this case?
