Can we get a more descriptive error when uppy-server cannot be reached

In my case, the error was:

Failed to load https://server.uppy.io/drive/authorized: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://vimeo-uppy.now.sh' is therefore not allowed access. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

But it'd be nice to see: Failed to reach Uppy Server at '<url>' I think.

This is probably a client side issue—I think fetch purposely doesn't tell JS much about what happened, but we could def do something like "Could not reach Uppy Server" or something.

Hah. got sniped!

@kvz yes, this seems to me like a client issue no?

[kvz]

I think so yes! - Will move it!

Moved to client repo 👌
