Hi William1,

Unfortunately the result has not changed, but actually the log shows differences from the previous test which seem to indicate the problem in the certificate.
Indeed, the error is due to the authentication scheme that should depend on the type of algorithm used for the generation of the certificate key.
Can you recover the type of algorithm used in that phase?

Anyway, you could verify your certificate using this tool: https://www.ssllabs.com/ssltest/

You have to indicate the url of your Lightstreamer server and in the results you should see all the connection tests from various types of clients.

Regards,
Giuseppe
