SEC_ERROR_INADEQUATE_KEY_USAGE when accessing the webGUI from Firefox
-
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.

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 generateguicertOk, this fixed the issue! Thanks for the help.

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" -

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

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.
