I have all of my cnames created and ready to go but under SSL/TLS>edge certificates they all show the SSL certs as pending. it looks like they are trying to validate by reaching out to www.somedomain.com/.well-known/pki-validation/ca3-178b534511324722a534090dd5c5941c.txt
How do I validate these certs? do I need to upload a file to my servers?
Or should I purchase a cert and upload it?
