I am hosting my website in the digital ocean server droplet. I have done it before, but now I need to obtain a certificate as well. If i host my application without configuring certificate I can access it both by ip and by www.forcecommit.com domain name. But trying to obtain a certificate and running this command:
sudo certbot --nginx -d forcecommit.com -d www.forcecommit.com
I get this error:
Obtaining a new certificate Performing the following challenges: http-01 challenge for forcecommit.com http-01 challenge for www.forcecommit.com Waiting for verification... Cleaning up challenges Failed authorization procedure. forcecommit.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: unknownHost :: No valid IP addresses found for forcecommit.com IMPORTANT NOTES: - The following errors were reported by the server: Domain: forcecommit.com Type: connection Detail: unknownHost :: No valid IP addresses found for forcecommit.com To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA 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 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. - Your account credentials have been saved in your Certbot configuration directory at /etc/letsencrypt. You should make a secure backup of this folder now. This configuration directory will also contain certificates and private keys obtained by Certbot so making regular backups of this folder is ideal.
I am a little bit confused because I can ping that website and I get the response. What could be the problem?
