@happnatious1 Yes, I remember that now. But, I did not open port 80, seems like a security hole to me as well.
My plan, which I forgot, was to open up port 80 to do the update (certbot renew), and then close it again.
So, I did this, and I get the following error;
Saving debug log to /var/log/letsencrypt/letsencrypt.log
