Hi
The above registry settings are correct, enable for client and server.
Open a firefox page and click a site certificate. TLS 1.3 will be listed under security.
You should also enable HTTP/2 protocol for IIS (and your own browsing) - blazing fast:
Open your registry editor and navigate to:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters
Make sure you have the following entries:
EnableHttp2Cleartext REG_DWORD 1
EnableHttp2Tls REG_DWORD 1
Reboot.
HTTP/3 supported in Server 2022. Still checking if it will work in 2019 it uses UDP (burst) 443 with TLS 1.3
Kind regards
