I checked your domain name, and the problem appears to be that DNSSEC is enabled on your domain name. However, our nameservers don’t support DNSSEC, so any client that validates DNSSEC will refuse to resolve your domain name.
To fix this, please disable DNSSEC at your domain name provider.
Please note that these settings show the DNS records of your domain in the nameservers of your domain name provider. However, your domain name is using our nameservers, meaning these records have no effect on your domain name. Any DNS records you want to change have to be configured through our panel instead.
