SSL for unity transport

I’m Running a dedicated server(Windows server 2019) with unity transport and i have problem with SSL
i don’t know how to configure that…

i try this solution but i can’t figure it out yet Create a secure client and server | Unity Multiplayer Networking

what is “ServerCommonName” ?
why it use WithSecureServerParameters on Client side? there is WithSecureClientParameters also and i tested it but it doesn’t works…

Thanks for your help

Any help please :frowning:

Error appears in both client console and dedicated server console:

Secure handshake failure (likely caused by certificate validation failure).
