I do not see the response when I request https://xyz.sbx-bp.fifthrail.com/, either in the Worker quick editor, nor in a browser. The DNS routes correctly, but I can’t see the output from my Worker.
Was there a specific hostname you’re testing it on? Unless you’re on an Enterprise plan, you can’t proxy () wildcard subdomains. And, as that’s a third level subdomain, you’d need a special TLS/SSL certificate for it.
I have a SSL cert for this domain. I’m looking in the account and I can’t find anything to tell me what plan I’m on but I think it’s an enterprise plan. Where would I find that?
