Hi guys, I got a similar problem. Although,. The server connects to my server and certbot replies properly. The result is Timeout during connect (likely firewall problem) , though.
My domain is: liveseller.in
i ran command certbot-auto --dry-run certonly --no-bootstrap --no-self-upgrade --webroot -w $DOC_ROOT -d liveseller.in -d www.liveseller.in
after hitting above command certificate creation dry run successfully passed.
but when i create the certificate using below command
certbot-auto certonly --no-bootstrap --no-self-upgrade --webroot -w $DOC_ROOT -d liveseller.in -d www.liveseller.in
It Fails, and giving error Timeout during connect (likely firewall problem)
