Connection Error in Xamarin Forms

[LumiProj]

Hi

I am using ejabberd server and connecting through the static ip of the server , It is working fine in windows and console apps but on Xamarin forms I am not able to even connect both in android and iOS.

This is error on Android.

I'm sorry, but what's the error? Where's the error message?

[LumiProj]

This is an error which I am getting during connection.

"Connection refused" means connection was blocked on server side. Make sure you are connecting to correct ip and port and it is not blocked by firewall

[LumiProj]

Well after firewall setting I resolve the previous error but now I am getting different error.

This is my development server without ssl so is there any restriction to access only from https.

Thanks

This error means you have configured tls on the server but with self-signed certificate. You can either install this certificate to your device as trusted or fully disable tls in server configuration.
Alternatively, you can comment out tls initialisation in this library but this can break connectivity to correctly configured servers.
