"session id context uninitialized" - reconnection error using Smack based client

[grigoryfedorov]

Hello!
We have a problem with Xabber (based on Smack 4.2) and jabberd2 server.
First connection is ok, but other reconnection attempts fails with SSL handshake error.
We use plain text auth now, and verify-mode='5', it work normally with verify-mode='0'.
jabberd2 version is 2.5.0

I'm attaching both server and clients logs here: https://gist.github.com/grigoryfedorov/2875a7b084636e43e8ca7960004e64c3

Here is the topic on Smack dev's forum: https://community.igniterealtime.org/thread/60589
but @Flowdalic thinks it is server issue.

@ungifted is the server owner.
