I have NGINX configured to only support TLS version 1.3 However when I go to https://check-your-website.server-daten.de/
It shows the error
Error creating a TLS-Connection: TLSv1.3 found, but no connection via TLSv1.2 possible. Please activate TLSv1.2
Isn't enabling only TLSv1.3 much safer? Why do we still need to enable TLSv1.2?
