I setup a Ubuntu 16.4 and Apache and tried using certbot and tried different way to obtain certs but always come up with:
Timeout during connect (likely firewall problem)
If I try with “-debug-challenges”, and try to connect to those it usually take < 100ms. What are some options I can try?

Can you connect from another computer? Another network? Another ISP? Another country? If the hostname has an IPv6 address in the DNS, is it correct and working? Could there be a firewall or networking issue?
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
