Unable to setup certbot properly with nginx + rails
I’m running command to test it:
$ sudo certbot renew --dry-run
And get this:
WARNING:certbot.renewal:Attempting to renew cert from /etc/letsencrypt/renewal/my_website.com.conf produced an unexpected error: At least one of the (possibly) required ports is already taken.. Skipping. ** DRY RUN: simulating 'certbot renew' close to cert expiry ** (The test certificates below have not been saved.) All renewal attempts failed. The following certs could not be renewed: /etc/letsencrypt/live/my_website.com/fullchain.pem (failure) ** DRY RUN: simulating 'certbot renew' close to cert expiry ** (The test certificates above have not been saved.)
It’s because nginx is running. But: how is it supposted to work? Stopping nginx and my website twice a day to check and possibly renew a certificate won’t be a wise way to go
How to fix it?
I’m using nginx + rails.
In cron I have this job:
$ sudo certbot renew
