Failed to renew my domain's SSL certificate

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

devrh1.kal800.com

I ran this command:

certbot renew -v

It produced this output:

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

Processing /etc/letsencrypt/renewal/devrh1.kal800.com.conf

Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: devrh1.kal800.com

Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

Welcome @kal800

It looks like port 80 is blocked by a firewall or similar. The HTTP Challenge (what the --nginx plugin uses) requires your nginx server to reply to HTTP (port 80) requests.

I can see your port 443 open but not port 80.

The Let's Debug test site is helpful to test changes you make

What about the second error?

There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see Failed Validation Limit - Let's Encrypt

You have to wait an hour before making another request to the production Let's Encrypt system. It only tolerates a certain number of failures per hour.

You can use Let's Debug right now as it uses the LE Staging System.

"What about the second error?"

When testing and not sure if things will work, always use the --dry-run flag till you know it works.

Example: certbot renew --dry-run -v

Once the error is determined and fixed, remove dry run option.

As mentioned, this is probably a result of too many "real" attempts (w/ errors).
