      hello,

      i have the same issue.
      I try the way from pascal, but nothing changed. The doc says to remove the cert9.db file after closing ff. In the folder i found the cert8.db too.
      if i remove both (i have renamed) than ff works.

      bye woodym

        So one thing that a corrupted cert cache doesn't explain is why did it work from your other site? Different profile being used for firefox? Does the other site do a ssl offload or mitm proxy?

        Did you cert cache become corrupted after you had tested from site 2, to pfsense1 and you didn't go back to test if still worked from site2?

          No proxy on either site. In terms of webgui configuration, both sites have the same exact settings. Same profile being used with Firefox and I'm also using v69.0. I've tested this with two clients with the same exact result where as long as they are on site1's network it present this error.

          Details of certs as requested:

            Those are certs on pfsense.. If it was actually in use it would show it. See the in use "webconfigurator" yoru other freerad cert has ZERO to do with you accessing the webgui.

            I don't see a san setting on that cert.. And prob not since its from 2016.. Create a new cert...

            see how mine has SAN:
            san.png

            I can tell you for sure that any modern browser is prob going to balk at no san entry.

              We have seen some recent browser updates fail when a non-server cert is used for the GUI. Some non-SAN certs started failing years ago.

              You can make a fresh GUI cert from the console with current best defaults with pfSsh.php playback generateguicert

                Ok, I'll try that route. How can you explain pfsense2's webgui working with no issues though? Here's the cert details:

                c8ed74e2-1d2b-4142-90b8-d22fce7a6fae-image.png

                There's also no SAN for the webConfigurator cert. And yes, I know that the FreeRADIUS server cert has nothing to do with my issue but I just included it in the screenshot anyway.

                  No clue - but what I can tell you happens alot is users say they do X, when they actually do Y... For all we know your hitting the other pfsense via http vs https. Or something silly like that.

                    The Key Usage browser error is almost certainly not SAN-related, but the GUI cert not having the bit set to act as a TLS Web Server (or the browser not seeing it for some reason).

                    Either way, generating a new proper cert should work around it.

                      I totally get that. And this is why I'm providing all screenshots that you need to prove what I'm claiming is true. I'm trying to be as troubleshooting-minded as possible here. And no, I'm accessing both through https. There'a nothing silly going on here because this is not really my first time handling pfsense but this issue isn't really familiar.

                      Anyway, I'll juet recreate the cert and be done with it.

                        The main reason that's the first step is because that's all we can really do. If the browser doesn't like an old certificate, but it does like a new one, then all you can do is generate a new one. We can't retroactively fix old certs, but when we find out about new/better defaults, we can fix the default cert code to comply for new certs.

                        The only actionable thing for us would be if a new GUI cert also failed.

                          That cert is prob from like 2.2.6 of pfsense or even before, since that is the lastest version of pfsense that was released that could of created that cert. Mar 8, 2016

                          JimP would know how many changes have happened with cert creation since that version and now ;)

                          Which one of those works and the other doesn't one was in Mar and the other in MAY, so you could have actually quite a bit of difference in pfsense versions that could of created those certs.

                          2.2.6 latest that could of created the mar one, but 2.3.1 could of been used to create the may one.

                              I am using windows + firefox and also Avast . pfsense is in a VM.
                              I got the same error SEC_ERROR_INADEQUATE_KEY_USAGE
                              Looking at certificats in firefox in Servers tab I found pfsense...
                              This entry should be deleted
                              It was "generated by avast! antivirus for self-signed certificates"

                                  and you see what cert is used by pfSense, what SAN, if the dates are ok, etc.

                                  This :

                                  will generate a new cert.
                                  Firefox won't trust it at first, but you can overreirde this. because you know that "https://192.168.1" or "https://my-pfsense.my-network.tld" IS your pfSese and not some hacked site.

                                  You can also use the console access to reset GUI access, so that http://192.168.1.1 is useable, so you can inspect with the GUI what the issue is.
