I checked your domain, and it seems that this issue is caused by the DNS configuration of your domain.
Specifically, it seems that DNSSEC is enabled at your domain provider. However, our nameservers don’t support DNSSEC, so the security check of DNSSEC is failing.
Seeing how your domain appears to be registered with Squarespace, this is probably what you need to do:
As for the SSL error in image2, it seems that you have uploaded a Cloudflare Origin Certificate. However, Cloudflare Origin Certificates are NOT valid SSL certificates. They can only be used to secure the connection between your hosting account and Cloudflare, and are not accepted by browsers.
To fix that, you can either switch your domain to Cloudflare so Cloudflare can handle the SSL used to secure the connection between your visitors and Cloudflare’s servers, or you can replace the current certificate with a certificate from a trusted SSL provider. You can use our free SSL certificates tool to get such a certificate.
