Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Sorry I am new here. I have used the ZeroSSL.com site to generate the needed SSL certs for our Kerio mail server for about 2 years. For some reason my first cert of my chain is showing expired on 7/24/19. I don’t understand as I have done the same steps that I normally performed for the last 2 years. The https://mail.sibex.com comes up normally. The SSL checks out find. But when I go to https://checktls.com I get an error about:
EXPIRED: Certificate 1 of 3 in chain: Cert VALIDATION ERROR(S): certificate has expired
So email is encrypted but the recipient domain is not verified
Cert Hostname VERIFIED (mail.sibex.com = mail.sibex.com | DNS:mail.sibex.com)
Not Valid Before: Apr 24 21:44:57 2019 GMT
Not Valid After: Jul 23 21:44:57 2019 GMT
Yes I restarted the service and that changed nothing so I restarted the whole server and that changed nothing. I then stopped the mail services and manually added the cert and then started the service. I then went through the steps and requested a new cert on the off chance I goofed or the cert file was damaged. Nothing has changed this issue.
You fixed it for me. Or atleast pointed me in the direction. When I checked our filter it was still using the old cert. I updated that and then we were working correctly again. Thank you!
