      Hello:
      via HAProxy (fax.mydomain.com)- "503 Service Unavailable - No server is available to handle this request"

      Direct (x.x.x.x) - "ERR_SSL_VERSION_OR_CIPHER_MISMATCH"

        Which has ZERO to do with pfsense - ZERO.. You don't go through pfsense if your directly accessing the machine, so no it wouldn't have anything to do with pfsense updating to openssl..

        But yeah if you have something going on with it, then makes sense that haproxy would also complain. Fix it so your direct machine can access it.. And your haproxy issue most likely will be fixed as well.

          I guess it is related to openssl 3.

            Not on pfsense it isn't - because when you access it direct and your seeing this error.. Pfsense isn't involved at all.. Maybe if you updated openssl on this device that is hosting your service?

              I know, that direct access has nothing to do with pfSense.

              I just sent the error code, in order to understand the issue, whilr direct access.

              The device is multitech fax finder FF130, I don't think I can update the openssl.

                @braunerroei if direct access isn't working why would you think it should work through haproxy?

                Like saying my car wont start when I sit in and turn the key.. But there is something wrong with my remote start because that isn't working ;)

                  @braunerroei Wait, you were not performing SSL offloading? ... You had HAProxy in TCP mode? ... Then ... the cert you configure for HAProxy via ACME does nothing... Like it doesn't exist

                      @braunerroei Can you disable SSL on the machine and put it behind HAProxy in SSL offloading mode?

                          What he means by that is just let haproxy handle the ssl, and make the connection via just http to the service behind.. Not both doing ssl.

                          As I stated before and asked for clarification on from you..

                          offload.jpg

                          I let haproxy handle the ssl with the client, and it just talks to the backend via normal http. NO ssl..

                              @braunerroei port 443 is almost always going to be ssl.. From the service run it - have never in all my years in the biz seen a server listen on 443 that was not using https.

                              Can you just talk to this 10.1.1.108 vi http://10.1.1.108 ? which would be port 80

                              example - here is opening up one my servers just directly accessing it on that port 8282, but just via http

                                When I access the machine directly using http, it redirect to https.

                                I tried to access using haproxy - frontend that listen to 80, and backend with 443 - no success.

                                  @braunerroei well set your machine to not redirect to 443, or fix whatever problem it has with its ssl cert installed on that machine. Because if you can not access it directly via https://fqdn then something is wrong with the ssl on it. And would explain why haproxy is complaining as well if your browser on your machine can not even access it directly.

                                  Is it the box itself redirecting you to https, or is your browser because of hsts?

                                      @braunerroei well stop it from doing that, can you not just disable https on it? And use just http? Or fix whatever is wrong with its cert..

                                      Can you not just create a cert via the cert manager and pfsense and use that on it.. Pretty sure there is a way to get haproxy to trust them, or a way to not have it check the cert, etc.

                                      but can tell you if you can't even get your browser to get to it via https directly, then haproxy is going to have a hard time as well.

                                        You can just connect a modern computer with your VoIP account from the ISP via App, get a cheap call center (grandstream or something), or even put a pcie pstn modem on a PC, they will all handle fax...Even fax and imaging of Windows can handle that. That thing will never again play with other devices. I read the manual. It's pre-WindowsXP...
