pfSense certificate
-
Yup could be. I use Firefox here and only ever have to allow the cert exception once per device.
What actual error is shown?

hey there,
I don't think it is a question of expiring...rather it seems to me, it is a question of "does Firefox already know about your self-signed cert?"
I use certificate manager on pfsense to make my own CA and use that to issue my own ssl certificates (and user ones as well). So in my LAN I have https active, using self-signed certs for servers at home (and a self-signed webGUI cert for pfsense instead of the default one).
BUT: you need to make that issuing CA known to your browser.So: export your CAs cert, import that to Firefox (settings > security > certificates I think) and then...it should no longer give out warnings and you do not need exceptions any more (since your browser sees your self-signed certs and trusts your issuing CA).
At least that's what I suggest... :)
-
@the-other Thank you for the reply. I tried importing the certificate to Firefox, and Firefox said there was no need since it already had the certificate.
So perhaps this is not a certificate issue.
-
@hspindel It’s likeky because you have set a validity span that is too long on your self signed certificate. I think the limit is around 390 days right now - otherwise the browser will declare the certificate invalid. Those limits are expected to drop further in the future i think
-
Sure you imported the ca one? First export from pfsense...I did not mean the ssl server cert, just to be sure.
@keyser
I read about limited lifespan acceptance too. Still, my certs have 3650 days and still got accepted... -

Was able to reproduce the issue. Actual firefox message is:
Warning: Potential Security Risk Ahead
Firefox detected a potential security threat and did not continue to <local IP>.
Issue is most likely with the website and there is nothing you can do to resolve it.
-
Does it tell you what the issue is?
The usual warning from the self signed cert is:
But you can just accept that and it won't usually ask again.
-
@stephenw10 Yes, that is the exact same warning screen I see. Unfortunately it reappears no matter how many times I accept it.
-
Hmm, that has to be a security setting in Firefox.
