Hello I have recently upgraded an ubuntu server from 16.04 to 18.04. Certbot stopped working properly after that. I am trying to figure out how to re-configure/recover. I am using nginx and certbot-dns-cloudflare. The version of certbot is 0.27.0.
certbot prompts me to use certbot certonly to regenerate/reconfigure everything. Since I need to reconfigure everything, I want to do everything properly.
First question I have is should I aim for cerbot v 0.31.0 instead of trying to make 0.27.0 work?
First problem I have is that despite using certbot certonly --dns-cloudflare-credentials /etc/nginx/cloudflare.ini command I get bellow error when I try to test if I can run auth at all.
“Client with the currently selected authenticator does not support any combination of challenges that will satisfy the CA”
I am having a bit of a difficulty on where to begin troubleshooting this.
