TimeOut Issue on Initialize

[nicomulr]

Dear Jim,
I'm contacting you this way, because I'm struggling getting my Docker BWALink working.
I have a balboa WIFI Module in place.
I'm getting following Timeout error
/usr/local/bundle/gems/balboa_worldwide_app-2.1.5/lib/bwa/client.rb:42:in `initialize': connect(2) for "192.168.1.99" port 4257 (IO::TimeoutError).

I'm not sure which port is the right one. I've tried 8899 as it is in your exemple and 4257, which seems to be the standard port for balboa.
But in both case, I cannot connect.
Any help would be much appreciated!
Thks in avance and BR
Nicolas
