@piba Thanx for the help man! Now, yesterday I have already tested a bit with a backend and frontend, but I ran into problems...I will create a new issue to explain what I want to achieve and what errors I ran into (whithout above settings and rules, I guess beside safety this doesn't affect the workability of ACME/HAproxy ?)

@vito So what did you configure to attempt to get to above goal?

@orionis Any feedback?

@simbad please create a bugreport https://docs.netgate.com/pfsense/en/latest/development/bug-reports.html

Squid version in pfSense 2.5/21.02 is 4.13: [2.5.0-RELEASE][root@xxx]/root: pkg info squid squid-4.13 Name : squid Version : 4.13 please test and leave your comment on https://redmine.pfsense.org/issues/10608

Anyone have any ideas?

@sraman This config does not look like it would be generated by the pfSense haproxy package like this.. are you sure it is the one used? the config seems okay by itself...

I was not able to update squidGuard package, process stucked on Initialization. So I disabled squidGuard and Squid, remove SquidGuard package, but unfortunately was not able to install the new version cause of stuck on initialization, so I just backup all and did an upgrade to 2.5.0 and it finished successfull. For now, my problem is solved, thanks a lot.
