Redirect pointed to worker - DNS RESOLUTION ERROR

I simply made a worker, it works great! So now I want to redirect traffic of a subdomain to that worker, but I get a massive DNS RESOLUTION ERROR.

Why wouldn’t a redirect to a worker work?

Ok even further weird issues.

The CNAME does work for me. I can even connect to a vpn and it works. But as soon as I use an external service to try and access the domain, it gets the DNS RESOLUTION ERROR. But not my machine. How does that work?

Even my phone on mobile data got it for 2 page loads, and now it works fine…

Ok, final update.

After 13 hours, no issues anymore. All machines that are redirected to the worker work fine.

Any idea what was up?
