Connection cannot be established successfully between an Android client and Windows server

[junbo75]

Describe the bug When tried to connect an Android client to a Windows server, I got log messages on both of the client and server side about the outgoing/incoming connection. However, the connection wasn't established successfully and the client didn't load any level.

Steps to reproduce Steps to reproduce the behavior:

1. Build Asset Processor and MultiplayerSample.ServerLauncher on Windows
2. Create self-signed certificate using OpenSSL. Add the certificate and private key files under the project root.
3. Create an autoexec.game.setreg file under the project Registry folder with the following content:

{
    "O3DE": {
        "Autoexec": {
            "ConsoleCommands": {
                "net_UdpUseEncryption": "true",
                "net_TcpUseEncryption": "true",
                "net_SslExternalCertificateFile": "<certificate_file_name>.pem",
                "net_SslExternalPrivateKeyFile": "<private_key_name>.pem",
                "net_SslExternalContextPassword": "<password>"
            }
        }
    }
}

4. Modify https://github.com/o3de/o3de-multiplayersample/blob/development/autoexec.cfg to add the connect <windows_server_ip> command
5. Process all the Android and Windows assets using Asset Processor
6. Build MultiplayerSample.GameLauncher following O3DE instructions
7. Deploy MultiplayerSample.GameLauncher to the Android device
8. Remove the connect <windows_server_ip> command from autoexec.cfg and start MultiplayerSample.ServerLauncher on Windows using the MultiplayerSample.ServerLauncher.exe --console-command-file=server.cfg command
9. Launch MultiplayerSample on the Android device

Expected behavior Android client is able to connect to the server and game level is loaded successfully

Actual behavior

• Got a message from the Android client: "New outgoing connection to remote address: 192.168.13.104:33450"
• Got a message from the Windows server: "<11:07:33> (Logger) - New incoming connection from remote address: 192.168.13.48:44146"
• No log messages on either the client or the server side about the connection status updates and no level is loaded on the client side.
