I wanted to deploy a preview version of my worker (Hono API basically) and configured two environments in the wrnagler.jsonc "preview" and "production".
Since I deployed from GH Actions I modified my actions workflow to include the environment.
That somehow broke everything and created two completely new workers "xxx-preview" and "xxx-production".
I deleted those two now and now use github integration directly.
However I now can't use the custom domain anymore. It is configured and also displayed in the dashboard but no requests would go through to it.
