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. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: (redacted)
I ran this command:
certbot issue command
It produced this output:
Unable to connect ACME API (DNS resolution failed OR Connection Failed)
My web server is (include version): (redacted)
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): latest
Here's a thing. I'm blocking CloudFlare with nftable firewall and when I tried to issue certificate for my site it failed miserably.
Turns out your ACME API is on Cloudflare server.
Could you stop using it and use your own server? Other *.letsencrypt.org servers are running on Akamai. Do so.
