Can't Register A Certificate For A Specific Domain

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: 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 "" --preferred-challenges "dns,http" --domains "" Saving debug log to /var/log/letsencrypt/letsencrypt.log Some challenges have failed.

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,


It's not possible to literally get it from the outputs you've posted (the NPM error you've posted does literally tells us nothing except that it failed), but I think it's a DNS issue. Your domain is having serious DNSSEC issues. See | DNSViz for example. When trying to resolve your domain with DNSSEC enabled resolvers, it will fail.


Yes, sometime we're not able to resolve this domain for certain networks.

May I please know how to fix this? I already contact my registrar and they say everything is okay on their side with the DNS records.

All my other domains are working just fine.

Your own domain itself does not have DNSSEC enabled, while the .se nameservers do have a DS resource record for, which does mandate DNSSEC for that domain.


Is is possible to enable DNSSEC and if yes, how to.




I'd send an email to my registrar asking they if this can be enabled.


That's probably the best step indeed.
