Hi everyone,

I’m having problems with SSL certificate renewal. My Let’s Encrypt cert didn’t auto-renew, and now webmail and SMTP are showing certificate errors.
Has anyone run into this? What’s the best way to fix it and make sure renewal works automatically in the future?

Thanks!

Try to run it manually with --dry-run. Also, send some logs.

How did you request ssl certificate? Use the command line tool "certbot", or the builtin cert management offered by EE?
Does it report any error?

I used the built-in certificate management offered by iRedMail EE, not the standalone certbot command.
When the auto-renewal tried to run, it didn’t seem to update the certificate, and both webmail and SMTP started throwing certificate errors.
I checked the logs under /var/log/letsencrypt/ but I didn’t see any obvious error messages, just that renewal was attempted but no new cert was deployed.
