I used to renew my certificate every 2.5 months, with the exact same command. It used to work, but started failing this time. I have tried using both letsencrypt-auto and certbot, but both are failing.
Since my server is behind cloudflare, I use the webroot plugin. I noticed that, in other topics people mentioned about disabling IPv6. I have disabled IPv6 in cloudflare. And still I get the same timeout issue.
I ran this command:
export DOMAINS="-d codiva.io -d kasadara.com -d www.codiva.io -d www.kasadara.com"
mkdir -p $DIR && ./letsencrypt-auto --renew-by-default certonly --server https://acme-v01.api.letsencrypt.org/directory -a webroot --webroot-path=$DIR --agree-dev-preview $DOMAINS
sudo service nginx reload
It produced this output:

Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
