I get unable to set SSL cipher list to 'PROFILE=SYSTEM' errors when reloading haproxy :

Any idea ?

It’s not aware of this syntax.

Why do you think you can set ciphers to PROFILE=SYSTEM?

I don’t really know, I took these lines from haproxy v2.4.17 RockLinux rpm package :

ssl-default-bind-ciphers PROFILE=SYSTEM
ssl-default-server-ciphers PROFILE=SYSTEM

Removing them and reloading HAProxy solved my problem.

Those could be variables that Rocky replaces before passing to haproxy.
