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: meijo.se
I ran this command: Using Nginx Proxy Manager, I'm pressing on "Save"

It produced this output:
Error: Command failed: certbot certonly --non-interactive --config "/etc/letsencrypt.ini" --cert-name "npm-96" --agree-tos --email "proxy-dc@zawack.ca" --preferred-challenges "dns,http" --domains "meijo.se" Saving debug log to /var/log/letsencrypt/letsencrypt.log Some challenges have failed. Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details. at ChildProcess.exithandler (node:child_process:326:12) at ChildProcess.emit (node:events:369:20) at maybeClose (node:internal/child_process:1067:16) at Process.ChildProcess._handle.onexit (node:internal/child_process:301:5)
My web server is (include version): I'm running Nginx Proxy Manager v2.9.4
The operating system my web server runs on is (include version): Ubuntu Server 20.04 LTS
My hosting provider, if applicable, is: Seflhosted.
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Nginx Proxy Manager v2.9.4
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
Also I wish to add, creating certificates for sub domains also fails. However, it works for all my other domains.
Best regards,
Guillaume
