Running caddy under docker with commercial certs where ports 80 and 443 are NOT available to caddy

Are there known issues between this (OLD) OpenSSL client side that Ubuntu uses on EC2 and What TLS library is Caddy using?

It really looks like the “handshake” between GOs lib and OpenSSL (in this case) is erroring out.

It should be easy to reproduce.

OpenSSL 3.0 and Go:

  • Go 1.18 and above: Go 1.18 introduced the crypto/tls package that supports OpenSSL 3.0.
