Trying to install certifcate and getting Error Code 403

Error code403: urn:ietf:params:acme:error:unauthorized": Invalid response from http://mspp.org/.well-known/acme-challenge/jfYVr500ZXQpqky5vlz85ZBivodaFFkpPeMk5Mze_2g [35.186.238.101]: “<!doctype html><html lang=“en”><meta http-equiv=“content-type” content=“text/html;charset=utf-8”><meta name=“viewport” con” (order URL: https://acme-v02.api.letsencrypt.org/acme/order/3435271/5333800836)

The domain mspp.org is not pointed to our nameservers and thus not currently hosted through Reclaim. It looks like the domain is registered through Godaddy and currently pointed to “cashparking.com” nameservers based on the information at Whois mspp.org. Only domains hosted on Reclaim are eligible for free certificates.

How can I point it to the Reclaim nameservers.

You can log into your GoDaddy account and repoint the name servers to the following…

ns1.reclaimhosting.com
ns2.reclaimhosting.com

GoDaddy has a support article explaining the process here. You’ll want to choose the Enter my own nameservers (advanced) option.
