Hello,
I'm trying to install the Let's Encrypt SSL Certificate on my domain, but I always receive an error.

Your registrar is saying that your domain is DNSSEC-signed, but your DNS server isn't actually signing anything. This means your domain name doesn't work at all. (Not just for getting a certificate, but in general.) You need to fix your DNS server to actually sign the records, or configure your registrar to say that the domain isn't DNSSEC-signed.

Thanks for your clarification, I asked my registrar to remove the DNSSEC and they just removed it now. Is that the correct action to remove the DNSSEC?
