level 3 CA certificate expired in new certs for domain

Hi, I've been having some issues with SSL certs showing as "expired" since the #3 certificate in the chain is expired (included below). Am I doing something possibly wrong? Or is this a real error or expired certificate. ***update*** I just checked and the WHM server host #3 certificate is the same CA (I think) but correct one expiring in 2038, ***update 2*** When forcing a WHM update check, it verifies certificates. I just came across this gem which I guess reveals the issue:

[2021-09-13 12:28:56 -0400]      [/usr/local/cpanel/bin/checkallsslcerts] The "cpanel" service"s SSL certificate is invalid. (Certificate #3 (CN=COMODO RSA Certification Authority,O=COMODO CA Limited,L=Salford,ST=Greater Manchester,C=GB) has 1 validation error: CERT_HAS_EXPIRED. Certificate #4 (CN=AddTrust External CA Root,OU=AddTrust External TTP Network,O=AddTrust AB,C=SE) has 1 validation error: CERT_HAS_EXPIRED.) The system will attempt to replace it with a new certificate from the cPanel Store.

the certificate chain for the WHM server hostname is fine, but the certificate chain for account domains is not.

I worked around this issue by switching to ECDSA, P-384 (secp384r1) certificates which uses a different CA. The above cert was RSA2048, and RSA4096 had the same problem I think.

the original issue is not resolved for RSA certificates, I just switched the key algorithm. The issue is still there.

Ticket 94362606 is being worked on with someone on my server as I write this. I have a second server on different IP addresses configured the same way and it received proper certificates.

September 15, 2021 14:29

Thanks for that! I do see that the ticket is under review. Please be sure to keep an eye out on your email for any updates. I'll be following the ticket as well.

Turns out my VPN tunnel was causing MTU problems, which was only evident by seeing that the CA bundle retrieval was timing out. Interestingly, I guess a different bundle (smaller?) is used for EC keys, which worked fine. Either way, it seems to be working fine now.

September 15, 2021 19:58

I'm glad that we were able to help resolve the certificate installation! If you have any additional questions or concerns, please let us know!
