Hi my companies ssl cert failed to renew yesterday, and I have been trying to figure out what could be the issue. I have checked with the MSP that manages our firewall and they say they aren't seeing any blocks that could indicate a firewall issue.
My domain is: avmail.alliedvaughn.com
I ran this command: sudo certbot renew
It produced this output: Saving debug log to /var/log/letsencrypt/letsencrypt.log
Processing /etc/letsencrypt/renewal/avmail.alliedvaughn.com.conf
Cert is due for renewal, auto-renewing...
