SERVFAIL Looking up CAA

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:
1.thr.ir.hosthorizon.xyz
I ran this command:
sudo certbot certonly --standalone
It produced this output:
Obtaining a new certificate

Looks like it's a DNSSEC issue:

You could try creating a CAA record in your DNS to avoid your nameservers sending the bogus response ... but I think it's probably best to ask Arvan about it, so that they can fix your zone for you.
