Signalr working in browser not in app


I have an app which uses signalR when i try it in the browser it works properly.
of course the connection is to an absolute URLץ

When i deploy the app to an android device it doesnt work.
I connected chrome to do remote debug to the app’s webview and i can see the network tab.

The negotiation is working and I can see result but besides that nothing works.

I assume it might be a permission\configuration issue since it works on browser.

Which steps should i take to make this work?

Thanks in advance!
