      Hello and thanks for reply
      to yours questions:
      It's not a browser cache, I try with a test website like webpagetest.org
      I tried with disabling redirect, but no changes
      You're right for NAT, I disabled the NAT rule and keep the firewall rule
      How can I be sure it's listening properly?

      Thanks
      Benoit

        In pfSense Diagnostics/Sockets page you can see which processes are listening on :443 (and :80 perhaps as well?), that should only be haproxy. The webgui nginx server should only be listening on your alternately configured :4433 port.

          Hi,
          I saw on sockets, everything seems fine, haproxy is earing wan_ip:80 and wan_ip:443.
          The problem is this website says it doesn't see http page and I want to install let's encrypt certificate and it says no connection to http.
          It's strange, but from the inside, that works correctly.
          Nginx wait on port 4433.
          thanks
          Benoit

            Umm?

            Where do you want to run the let's-encrypt client? On pfSense for haproxy's use? Do you forward the acme-challenge request to the correct place for the LE servers to see the file? How do you have haproxy configured? Can you share the haproxy.cfg ? (obfuscate IP, domainname, stuff if desired)

              I want to run let's encrypt on the server in the subdomain.
              The master domain is zelec.homelinux.net, the subdomain is dolizelec.zelec.homelinux.net. I use cerbot to install LE certificate.
              it reply:

                have you made a firewall rule on the wan to allow tcp access from any to wanip:80 ?

                  Is that correct as I've done

                      Thank you,
                      I'll continue to search with certbot why it doesn't want to work.
                      Thanks again

                        So now you should be able to use acme to get a certificate, after that the https site should be configured with it..

                          Previously you got the message "Timeout during connect (likely firewall problem)" .. I think that should be solved now.. So what is Certbot / LEservers saying now for error.?

                              Hello,
                              I solved things with certbot, but now my problem is port 443 goes to pfsense webgui instead of my haproxy backend.
                              I don't understand why
                              Thanks

                                Webgui is still configured on :4433?
                                Is haproxy still the only service listening on :443 ?
                                Is haproxy configured to forward traffic to pfSense webgui with some backend, maybe a acl doesnt match properly and sends the traffic to that backend then?
                                Do you have a nat rule that points 443 traffic to the webgui port?

                                  Hi,
                                  Webgui is on port 4433
                                  As I know haproxy is the only service listening 443
                                  there's no backend to webgui. For the moment, I have 2 frontend 1 for port 80 and 1 for port 443. and 2 backend for rhe same reason.
                                  I use a NAT rule for 443 but il's for my old server, and I disable it for test.
                                  My new server (in a subdomain) and my old server (with NAT) use apache. And when I try to certificate with LE, the reply is a nginx server reply in 443. As I don't have any nginx server, I suppose it's the webgui which is served by Nginx.

                                  Thanks

                                  Here my haprowy.cfg if that can help
                                  haproxy.txt

                                    That might be, but the pfSense webgui does not seem the send the <!DOCTYPE HTML PUBLIC which the certbot error shows, so if it is nginx then its a different nginx server than that running on pfSense.. i doubt its finding its way to the webgui.. your Apache server however does send that doctype when requested for a page that does not exist.. I think the certbot>letsencrypt request does properly land on the Apache server but maybe the token file was just not placed in the correct subfolder?

                                      You're right, I delete certbot and install a selfsignated certificate. That works correctly. The problem come from LE. As the server is empty, I will reinstall it.
                                      Thank you for your help
