Parse Error On Initial Connection To Firebase/Google Cloud Messenger

[Trucked Operations]

I'm receiving this parse error as soon as a connection to Firebase / Google Cloud Message Service has been attempted. I'm not sure if the error stems from not invoking the proper build methods or there's an error in using the SSLContext.

OUT: <?xml version="1.0" encoding="UTF-8"?><stream:stream xml:lang="en-US" to="xmpp.googleapis.com" version="1.0" xmlns="jabber:client" xmlns:stream="http://etherx.jabber.org/streams">

From the documentation: You must initiate a Transport Layer Security (TLS) connection. Note that CCS doesn't currently support the STARTTLS extension. By default this library uses StartTLS (as per the XMPP spec). Try creating a TcpConnectionConfiguration with a SSLSocketFactory set, which uses your SSLContext. It should then connect directly with SSL.

Perfect. The default SSLSocketFactory worked. Thank you!

SSLSocketFactory worked, I close this issue.
