Hi,

does anybody knows how to disable TLS 1.0 and TLS 1.1 Support and enable 1.2 & 1.3 in Traefik 1.7.20?
I've seen documentation for Traefik 2 but not for 1.7.

I would appreciate any help!

Thanks

Christian

Ok found in consul the key entrypoints.https.tls.minversion and set the GO ENV Var GODEBUG=tls13=1 for TLS 1.3

I added:

     environment:
       - "GODEBUG=tls11=0"
       - "GODEBUG=tls10=0"

But TLS checkers still show the site has having 1.0 & 1.1 enabled. How do we disable them?
