Worker works in editor, not when deployed

I have an issue where my worker-site returns error 1101. The thing is, when I run it from the editor I get a 200 with the expected payload, its only the deployed version that errors.

And I cannot find the logs anywhere, its seems these are only accessible to enterprise customers?

Here is the error page:

It could be how deep you subdomain goes and SSL related.
try blackbird-dev. instead of blackbird.dev.

You need to correct DNS and routing accordingly.

It looks like they’re using a custom certificate with a ton of subdomains and wildcards under subdomains. I’m able to load that URL.
