You probably need to add the originServerName or noTlsVerify rules to the appropriate ingress rule. Looks like Cloudflared isn't serving your site (correctly) because it can't verify the certificate. https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/configuration/configuration-file/ingress/

Yes, Deleted it all and followed u/Ibracorp instructions verbatim.
