TLS1.3 not supported in Windows Desktop Client

I just locked down my NC installation to support only TLS 1.3 and all desktop clients (v2.5.3daily-Win64) stopped working. All mobile apps and web browsers work perfectly.

Wireshark shows the desktop clients send Client Hello packets advertising TLS 1.2. The server then sends a fatal “protocol version” alert and gracefully closes the session before any TLS handshake occurs.

When should we see TLS 1.3 support?


You have to wait the 2.6.0 client who will be release the next week.


Great to hear. Thanks!
