      Sadly I never got around this after a huge amount of time for a fix, not even in 2.7.2 so I turned to OPNsense instead of waiting for 2.8.0.
      Missing some features from pfSense, but now I don’t have issues anymore to access the interface.
      Loved pfSense and the community but this was a big issue for me :(

        Hmm, odd. We don't really see that in 2.7.2 any longer. I used to be a much bigger issue. It pretty much always implies some php process running away though.

          Hello @stephenw10 and everyone.

          I've recently installed Pfsense 2.7.2 and kept on getting bad gateway 502.

          while troubleshooting I tried reverting back to 2.7.0 and after doing so, my pfsense IP no longer gave me 502, but after updating again to 2.7.2 i kept getting 502.

          I tried restarting php-fpm and it loads webgui before it says 502 again.

          I reverted to 2.7.0 and webgui is now working again.

          The only problem I have is I'm unable to use pkg manager due to version mismatch :(

          Can anyone help?

          Thanks everyone,
          Vector

            If you see 502 errors it's almost always because php failed for some reason. You should see something logged.

              I do see things get logged after accessing: tail -f /var/log/system_general.log

              It says: "[ERROR] 556088#100299 *88 connect () to unix: var/run/php-fpm.socket failed (61: connection refused) while connecting to upstream, cleint: [PFSENSE IP] server:

              And while running tail netstat -an | grep LISTEN
              It listens on 127.0.0.1.953.

              Would you please help?

                But nothing in the main system log?

                How is it configured? What are you running on?

                  I'm sorry, I'm a beginner.

                  Would you please explain further?

                    I mean a basic 2.7.2 install will run without php issues. So what configuration have to done to yours. Something there is causing it a problem. Maybe some package you added is exhausting the RAM for example.

                      I get your point; however, this issue occurs as soon as I do a clean install of 2.7.2
                      Without changing anything in the configuration at all.

                      I just set the IPs and the interfaces. pfsense WAN: 192.168.1.10 ISP router: 192.168.1.1 Pfsense LAN : 10.27.27.1

                      **Edit

                      I didn't add any packages and I have 16GB of RAM

                        Hmm, odd. What hardware is it installed on?

                        You are connecting to it from a client on the LAN?

                          It's on Dell Latitude 7490 i7-8650U CPU
                          And the installation was USB memstick.

                          Again, this issue only occurred on 2.7.2 and 2.7.1.
                          2.7.0 worked fine, and I had to update it because the package manager didn't work :(

                          Yes, the client is on the LAN but even when I try to access WebGui from the ISP's side it returns the same 502.

                            @vector88 said in 502 Bad Gateway, nginx:

                            this issue occurs as soon as I do a clean install of 2.7.2
                            Without changing anything in the configuration at all.

                            To be clear that's with the default config or after importing your config that works in 2.7.1?

                              Default config, just after assigning the WAN, LAN for Pfsense and connecting Pfsense LAN to a switch and an ethernet from the switch directly into my laptop and then 502 everywhere.

                                Does it allow you to connect at all? To complete the setup wizard even?

                                  Yes, just after going through the wizard, right after finishing and entering the same config on the wizard and finishing..... Reboots..... And then 502

                                    It shouldn't reboot after completing the wizard. Did you set some interface specific value?

                                      Yes it shouldn't reboot. But after finishing the wizard it does the same thing, I tried rebooting as an extra step

                                        Can we see the system logs covering time the wizard is run and immediately afterwards?
