      That is proxying the traffic. You will need to enter it manually.

        @stephenw10 We don't use a proxy server for traffic.

          If you have something scanning inside https then that is proxying the traffic to do so. The pkg command used to update will only work if you tell it to use that proxy directly.

          However on 2.7.0 you might also hit this: https://redmine.pfsense.org/issues/14609

            @stephenw10 OK lets me explain this better. The upstream GW inspects HTTPs traffic, it does not act as a proxy server. Entering the IP in the proxy section just breaks traffic. Every other device (including the current pfsense appliance) is routing traffic just fine. The only bit that is broken is the update option.

            And since I have imported the root CA cert why is pfSense still rejecting the cert as invalid as per the original error message.

              It may not use the word proxy but the only way to inspect https traffic is to proxy it. It's a transparent proxy but it probably still has a proxy port it can listen on directly.

              Can you use fetch at the pfSense CLI directly?

              [2.7.2-RELEASE][admin@t70.stevew.lan]/root: fetch https://www.pfsense.org

              Or curl?:

                  You may need to restart php or reboot if you have not done so since uploading the CA cert.

                  What version is your other pfSense device that is working via the proxy?

                    @stephenw10 I've rebooted multiple times, same result.

                    This is the only appliance I have.

                        So by that you mean just routing? Not that the current pfSense appliance is able to connect?

                        Is this something new that has just stopped? You recently added the proxy/filter?

                        You can just install 2.7.2 clean and restore the config. The proxy setting is fixed there.

                          @stephenw10 I've edited the /usr/local/share/pfSense/pkg/repos/pfSense-repo.conf from https to http only which allowed me to update to the latest 2.6 release.

                          I then changed the branch to 2.7 and exited the file again to try to upgrade but after running the command: # pkg-static clean -ay; pkg-static install -fy pkg pfSense-repo pfSense-upgrade It failed with,

                            Yes, just routing is working. I've inherited this setup from the previous admin. It must have worked at some stage in the past since packages are installed and I can't install them now.

                            Yes I can deploy a new CE release but the issue persists, so since I can't install packages this isn't a solution.

                              What should work here is to install 2.7.2 clean then set the proxy rather than trying to use it transparently. The proxy setting works correctly in 2.7.2.

                              Can you test that in a VM?

                              The pkg repos are https only from 2.7.0.

                              I would have expected the imported CA cert to work for command line connections. 🤔

                                For any other VM I have no need to define any proxy settings.

                                I know it won't be popular but I deployed OPNsense, imported my CA cert and was able to grab updates/packages without an issue. No proxy settings just defined the upstream gateway.

                                Since I have no visibility beyond my initial upstream GW I've no idea about which device is doing the HTTPs inspection so setting that IP isn't really an option or solution for me.

                                In my mind once I have imported the cert the HTTPS should just work. As a test I deployed the 2.7.2 release and also had the same issue once the cert was imported.

                                  Ok how exactly did you import the CA cert?

                                  Ah, you don't control the upstream proxy? Some other admin just gives you a CA cert to use and you're forced to trust they do the right thing with it?

                                    Testing here an imported CA cert is used from the OS trust store by curl from the CLI in 2.7.2.

                                    What error exactly do you see when you try that?

                                      Or try running: pkg -d update

                                      What error do you see there?

                                      Part of that output should include:

                                      * Couldn't find host pkg01-atx.netgate.com in the .netrc file; using defaults
* Hostname pkg01-atx.netgate.com was found in DNS cache
*   Trying 208.123.73.209:443...
* Connected to pkg01-atx.netgate.com (208.123.73.209) port 443
* ALPN: curl offers http/1.1
*  CAfile: none
*  CApath: /etc/ssl/certs/
* SSL connection using TLSv1.2 / ECDHE-RSA-AES256-GCM-SHA384

                                      And the imported CA cert should be in /etc/ssl/certs if the trust store box was checked.

                                        @stephenw10 In short yes, but as I mentioned this pfsense is the only system having an issue with the cert.

                                        We have an internal site which has the pem files available. I downloaded the file, edit in notepad, copy the cert and import it to the UI in pfsense as an existing CA and check the box to add to local trust store.

                                            Also is there some reason the issuer shows as self-signed?
