Unable to renew dry run

Help

I ran this command: sudo certbot renew --dry-run

It produced this output:

Saving debug log to /var/log/letsencrypt/letsencrypt.log

Processing /etc/letsencrypt/renewal/my-link.conf

Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.

How can this issue be resolved? Would using the webroot method work? I should also note that I tried stopping Nginx before running the command, but it still did not work.

The port conflict can be caused by running Certbot with --nginx option when nginx is not already running. There was probably a different error before that one.

That seems like something you ought to know if you're hosting a web site, doesn't it? Especially when the apparent problem is that that server is already running when certbot tries to spin up Nginx (because that's the way you've configured certbot)?

Yeah, you are not making this easy for us to help you by not providing requested info.

What do these show

sudo ss -pant | grep -Ei ':80|nginx'

sudo ps -eF | grep nginx

sudo systemctl status --no-pager -l nginx | grep master

The nginx that is running is not under the control of systemd. While that is technically possible it is not usually what people do.

That can happen if running Certbot with --nginx option when nginx is not already running. In that case Certbot starts nginx but not using systemd.

To start, kill off all those running nginx processes and start it normally. Or just reboot your server.

After that, make sure nginx is running. Check it with

sudo systemctl status nginx

If that looks correct show output of this. Do NOT run this if there is any error shown by the above status nginx command

sudo certbot renew --dry-run

NOTE: If you are running nginx outside of systemd please explain more details about that.

Thank you for your comment.
Successfully, Certbot is working on my server.

Best regards,
