HEADS UP: DST Root CA X3 Expiration (September 2021)

@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.

@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.

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.

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 ;)

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..

Nope, not only Bro., it also affected our NextCloud servers too

PS:

(Are you all right?
if you have time, we could talk this weekend, long time since I heard the new news from BR)

mcury

Oh, didn't know about NextCloud servers..

I'm all right, thanks for asking, and how about you?

I'll be traveling to Buzios/RJ this weekend, going to the beach hehe
I'll be back on Sunday night, I'll send you a message to give you some news about here, hope everything is better for you guys there in Portugal too =)

@daddygo How exactly do you have SSL Configured on NextCloud? on the Server itself using Acme or Lets Encrypt or with Haproxy? It was only the SSL Certs that were affected on pfSense but for Postfix and Dovecot Certs are all fine thats with Certbot.

jimp

This thread was only for the expiring CA from Let's Encrypt with the ACME package. It is not for issues accessing things as a client.

If you are using outdated versions of pfSense or other clients without a current set of up-to-date root certificates, read and post in one of the existing threads in the General pfSense Questions category for that specific use case.
