Error trying to get a certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: certbot certonly --standalone -d

It produced this output:

   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.

My web server is (include version): VPS

The operating system my web server runs on is (include version): CenOs 7

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 1.11

The name has two IPs:

Addresses: 9f93:8978:eeca:5487:799d:3121:1c96:f6bd

Neither of which appears to be open via HTTP:

curl -4
curl: (56) Recv failure: Connection reset by peer

curl -6
curl: (56) Recv failure: Connection reset by peer

HTTP access is required to validate the certificate request [when using HTTP-01 authentication].


@rg305 thank you... wel I must say it was a bit silly of me not thinking about that, as I work on several VPSs I thould port 80 would be open but it was not so now I opened the port and create the certs with no problems.
