Hi ManKeer,

At this point, maybe the certificate hypothesis as cause of the issue is no longer valid.
However, it seems appropriate to me to have as much information as possible about the issue.

Please, could you provide us with a snippet of the server log (lightstreamer.log) of a test case that fails?
We can start with the factory configuration of the log; then based on the results we may ask you to move to more verbose levels.

Thank you,
Giuseppe
