[solved] Another instance of Certbot is already running

Help

Hi @bv1,

As @rg305 said, first you need to be sure that there isn’t another instance of certbot running but as you said your server reboot unexpectedly during the renewal process… maybe certbot is not running but it left some .certbot.lock files behind.

If it is not running, check whether there are .certbot.lock files in your system.

find / -type f -name ".certbot.lock"

If there are, you can remove them:

find / -type f -name ".certbot.lock" -exec rm {} \;

And try again.

Cheers,
sahsanu
