Hi @l1349422030, it does not look like you have a certificate on your origin server but ssl on your crypto tab is set to Full (Strict). The best bet is to get a certificate on the origin (you can do that self-signed for free from the crypto tab). A less desirable option to get things working quickly is to set ssl to flexible to see if the site loads.

It seems the domain has an incorrect DS record, so validating resolvers like and are unable to resolve it.

(Mouse over the long red line.)

The “2371 13 2” part is correct, but the digest is wrong. Go to the DNS section of Cloudflare’s dashboard, and the DS records section of NameSilo’s control panel, and try again.
