Hi baalbaki,

This is a strange behavior, it seems that both sides are waiting for a network packet from the other side but then timed out.
Please could you specify the Lightstreamer server version? Is this error always the same or do you see different messages?
Maybe that it will be necessary to investigate further with a more complete snippet of server log (lightstreamer.log) and in case more precise instructions will follow.


Anyway, if you want to be sure that your server is properly configured with the tls certificate you can always test it with ssllabs: https://www.ssllabs.com/ssltest/
