Update,

The Certs are fine it seems to be a Firefox issue as Chrome/Brave Shows different I also checked it against https://decoder.link/sslchecker/ and checks out fine.

Thank for your help guys :)

[JeGr]

@violetdragon Ah so more of a browser/caching thing - yeah that's a pain in the ass. Good to see it fixed anyway so you won't run into issues at the end of the month :)

[VioletDragon]

@jegr Firefox seems to handle it differently. I've noticed that it only happens when signed into a Firefox account so not sure if the account saves the cache but it's a strange one.

The browsers / Windows have their own trusted root CAs. I expect that once the old ones expire/get removed/revoked from those built-in stores, the new chain will take precedence and show correctly.

[sergio.londono]

for testing while the SSL expire, We did:

Delete the expiring Root CA from the client browser.
login-to-view

Then, Open private browser:
login-to-view

@sergio-londono That's solved the problem, Cheers :)

Hi all.
We use pfsense 2.4.4 version.
I did all the steps and all looks ok.

However reading about openssl, will acme (or any other thing) have issues when renewing certs? Like acme accessing le api which use le cert naturally?

If so, is there a way to fix it as we are unable to upgrade.

Thanks.

[VioletDragon]

@maverick_slo why such a old version of pfsense? I would recommend updating.

While I would too - but I also have some units still on 2.4.4p3 - covid being the reason, with nobody on site.. And I can not go in - can not risk it. They might have to stay on that version until things really get back to normal. And I can be onside for update, and other remote sites have people there that can be my smart hands if things go belly up. Things normally go fine - but just not something can risk at this time. Maybe he is in the same sort of boat.. I hope he meant p3, this was the latest version before covid became a factor..

[VioletDragon]

@johnpoz that makes sense. I have worked with people that neglects updating or just too lazy to do updates. Certs should be fine providing you have done the fix in this thread. Openssl has been updated since. You can try doing a dry run to see if it fetched a fake Cert if it does then you will be fine until you can update.

[johnpoz]

@violetdragon I hear ya - you should always be current completely agree 110% Its kind of eating at me that they are not current ;)

But these are different times for sure.. Before this I would of pulled the trigger on a sunday evening from home on the update, even if version just came out on saturday ;) Because I knew I could just go in bit early monday if it went belly up..

So I am currently more willing to give some people slack on the update.. But yeah stay current I am with ya.

[VioletDragon]

Just thought i'd put this out there, you can verify your SSL Cert by using the following.

Tests using TLS 1.3
openssl s_client -connect yourdomain.com:443 -tls1_3  

Tests using TLS 1.2
openssl s_client -connect yourdomain.com:443 -tls1_2

My certs are fine
My question was actually if acme will have issues obtaining NEW certs from today onwards.

@maverick_slo

Noop.
Letenscrypt uses the new intermediate and root certificate to sign yours.

As long as the ACME package is renewing certs with ACME v2 you're fine. Not all of the older versions of the ACME package support that, but if that was a problem, it would have been failing for the last few months already. That's unrelated to this intermediate expiring.

I've even copied (edited) ACME package files from a current package version back to a 2.3.x install and it renewed a cert fine there with ACME v2 and got the correct intermediate after I cleared out the old one.

Acme didn't have problems in the first place. It assigned new Intermediates back like at the start of the year as the revocation was known well in advance. I have systems I haven't touched in over a year that run completely autonomous with acme.sh or certbot (or other LE clients) without a hitch. It's only when local certificate stores or wrong CA chains from the OS etc. mixed with "unable to (auto) update thing" come into play that things go wrong ;)

@jimp

This one worked for me
Now iOS devices get valid certificates

It seems that this problem is affecting Plex.. It appears to be solved now, but some old devices won't be able to connect through secure connections anymore..
