Unable to get a new certificate


My domain is: automation-lab.net

I ran this command: sudo certbot certonly --webroot --webroot-path=/var/www/automation-lab.net -d automation-lab.net -d www.automation-lab.net

It produced this output: (Last part of output) 2018-06-29 13:43:31,853:DEBUG:certbot.reporter:Reporting to user: The following errors were reported by the server:

Domain: automation-lab.net
Type: connection
Detail: Fetching http://automation-lab.net/.well-known/acme-challenge/n3rP_TKY-8LEQvfGlE9mu-q79F-azWy6P2NV8BsBp78: Timeout during connect (likely firewall problem)

To fix these errors, please make sure that your domain name was entered correctly and the DNS A record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are p$

My web server is (include version): Nginx/1.10.3

The operating system my web server runs on is (include version): Raspbian GNU/Linux 9 (stretch)

My hosting provider, if applicable, is: I am hosting this on my raspberry pi

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

I have enabled port forwarding on my router and i can verify that i can view the site on a browser.


I can’t access http://automation-lab.net/. (Or https://automation-lab.net/.) I can ping it, though.

Are you sure the DNS records are correct; your computer, router, modem or ISP aren’t firewalling it; it can be accessed from other networks; it can be accessed from other ISPs; and it can be accessed from other countries?
