Certbot Syntax Error

Help

My domain is: redspro.redangus.org

I ran this command: certbot renew

It produced this output:
Cert is due for renewal, auto-renewing…
Could not choose appropriate plugin: The requested nginx plugin does not appear to be installed
Attempting to renew cert (redspro.redangus.org-0001) from /etc/letsencrypt/renewal/redspro.redangus.org-0001.conf produced an unexpected error: The requested nginx plugin does not appear to be installed. Skipping.

I can login as root

No control panel

the .conf file is empty. How can I get this to renew? Manually is fine, I just need it to work. When I try and do it manually I get the following:
./certbot --nginx -d redpros.redangus.org -d www.redpros.redangus.org

It seems you don’t have certbot’s nginx plugin installed. How did you install certbot? What version is it (certbot --version)?

You might need to install the nginx plugin as a separate package. If you can’t find it, maybe you could use certbot-auto (which might be a good idea anyway, if your version of certbot isn’t up to date), or you could use certonly and reload nginx with a hook:

certbot certonly --webroot -w /var/www/whatever -d redpros.redangus.org -d www.redpros.redangus.org --deploy-hook "service nginx restart"

or possibly (with older versions):

certbot certonly --webroot -w /var/www/whatever -d redpros.redangus.org -d www.redpros.redangus.org --renew-hook "service nginx restart"

You might also need to delete the empty conf file, though I don’t think it does any harm to leave it as long as another correct one exists as well.
