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.

Let’s Encrypt offers Domain Validation (DV) certificates.
Thus you need to own and have control over the Domain Name you wish to obtain a certificate for,
from an ICANN Accredited Registrar.
For Let’s Encrypt to issue a Domain Validation (DV) certificate Domain Validation must happen
and it is a CA/Browser Forum Baseline Requirement.
Best Practice - Keep Port 80 Open
What IP addresses does Let’s Encrypt use to validate my web server?
Let’s Encrypt does not publish a list of IP addresses we use to validate,
and these IP addresses may change at any time.
Let's Encrypt uses Multi-Perspective Validation Improves Domain Validation Security - Let's Encrypt
Since these are Domain Validation (DV) certificates the Domain Name System (DNS) is used extensively in the validation process as well a allowing us to assist here on Let's Encrypt community.
DNS Queries need to give consistent results from any location on the Internet, all your authoritative DNS Servers for the Domain need to also give consistent results as well.
Testing and debugging are best done using the Staging Environment as the Rate Limits are much higher. Rate Limits are per week (rolling).
And to assist with debugging there is a great place to start is Let's Debug.
With them you need to Find and purchase a domain name as your first step.
That's funny, you're the second person today who's posted that their domain is mydomain.com. Are you sure you own that domain name? Or are you just using that as a placeholder for your real domain name? If the latter, please stop and tell us the real domain name.
