Greetings,
I’m currently searching for a way to implement accept-proxy & send-proxy-v2 to my haproxy instance.
My goal is that nginx (reverse proxy) is able to receive the IP address of the caller from haproxy instead of the haproxy ip.
Currently I have an issue that whenever I enable this, I get a SSL handshake error (more Details below).

The certificate is a public trusted by LetsEncrypt. Any ideas what could be wrong?
