Question TLS 1.3 disabled on plesk obsidian for windows

[clairertp]

Server doesn't pass test for TLS 1.3. Apparently it is disabled. Does someone know how to enable TLS 1.3 on plesk for windows?

TLS 1.3 is only supported on Windows Server 2022:

Protocols in TLS/SSL (Schannel SSP) - Win32 apps

The schannel SSP implements versions of the TLS, DTLS and SSL protocols. Different Windows versions support different protocol versions.

TLS1.3 is it supported? - Microsoft Q&A

Hi everyone, Is TLS1.3 supported in IIS on Windows Server 2016? I'm unable to find any documentation where it says if it is or not.
