I have a problem that is really hard for me to find the fault, I looked for information on all sides I made two million changes and I can't make SignalR walk in the mobile application created with Xamarin Android. The theme is as follows: from VS using the Android emulator the connection to SignalR works fine but when I publish the Android application and use it from my cell phone it doesn't connect and I can see the following error message from Windows Events:

I have an Azure VM but it does not have an Antivirus installed, only windows defender, I saw elsewhere that it could be the AV but I discard it.
The strange thing is that from the VS Android emulator I address the signalr path and it connects well. The webapp also connects and works well, it just does not work by running the application from the cell phone with Android (I tested it on several computers).
try to address with http and https and it works fine from the emulator but not from the Android app
Can you miss any permission from Xamarin Android?
I appreciate any help
