Are you using Project IDX by any chance? shorebird login needs the ability to start a local http server so it can receive a callback from the authentication provider (Google, in this case). This does not work on Project IDX.

One thing we could do here is warn about reachability. e.g. from shorebird doctor or otherwise.

shorebird doctor does include api.shorebird.dev reachability (it was recently added).

In this case I think oauth2.google.com is the unreachable URL?

The real fix for these is to fall back to remote-based OAuth, like what Firebase does:

https://github.com/firebase/firebase-tools/blob/master/src/auth.ts#L543
https://github.com/firebase/firebase-tools/blob/master/src/auth.ts#L399

firebase login --no-localhost will also do this explicitly and is what IDX does.

This should be really easy to do on the command line side. The only real work is on the web side. I don't know exactly what auth.firebase.tools does.
