Hi jvanhensberg,
Please refer to the inline comments of <https_server> parameter in the "lightstreamer_conf.xml" configuration file in order to properly configure your Lightstreamer server.
You should also refer to point 4) of "PRODUCTION_SECURITY_NOTES.TXT" and to "
TLS Certificates.pdf" documentation.
Please let us know if you need any further clarifications.
Regards,
Giuseppe
