I've moved your thread to the #help section, as I'm thinking your thread is more about getting help with issuance than you'd like to discuss something about issuance.
In the #help section, you would have been provided with a questionnaire, which is mandatory to fill out to get proper support. While you've already given us some answers, I'd like to invite you to answer all the questions nonetheless as good as you can. If you don't know the answer to a question directly, please say so in stead of leaving it blank. Here's the questionnaire:
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. https://crt.sh/?q=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:
I ran this command:
It produced this output:
My web server is (include version):
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):
This is probably the important part. Whichever ACME client you are using is trying to use DNS validation (updating your domain's DNS with an _acme-challenge TXT record to prove you control that domain). You need to look at how that is configured and that will depend on what tool you are using to get certificates.
