When trying to create a graph i instantly get this error:

> We couldn’t connect to that URL. Please double-check that it’s correct.

This is my endpoint URL: `https://trotty-server-dev.fly.dev`

What could I be doing wrong ? I’ve tried adding `Apollo-Require-Preflight` header as well but no success.

Thanks in advance for your help!
