Deploying my app to fly.io and experiencing this issue when attempting to sign in. After going from the Google Sign In Page back to the callback url at /auth/callback, white screen is loaded rather than the default orange spinner. Looking at the console, I see this (though I'm not sure if this is relevant to the issue. The same sequence when run locally functions fine The stylesheet https://domain-name/auth/callback/static/css/main.e6d1f72b.css was not loaded because its MIME type, “text/html”, is not “text/css”. The script from “https://domain-name/auth/callback/static/js/main.361a78ef.js” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.

hey @djarran - what does the network request say when the page is loaded? Do you see any errors?

it is not making any requests to auth/signinup route

yea but the browser must be sending a request to load the page itself - what do you see as the response for that?

sorry, not sure exactly what you mean but these are the only requests I see being made once visiting the callback url (where it is stuck)

right, so i was talking about the first request. It's a 200 as i can see

the above image is all I see in my browser console

im not sure whats being served by fly.io. Maybe it's misconfigured and it's not actually serving your react app

okay then

on fly.io?

until I signed out :/

right. So is netlify serving the react app correctly on that callback url?

from the looks of it, i guess not

yea. that's what i thought. So then please check your netlify settings

sure

im not sure either. Perhaps some netlify / react thing.

still trying to fix this issue. trying to implement my own UI and handling the callback using the examples provided

are you doing server side rendering?

no server side rendering, just wanted to deploy to a different host
