auth/timeout during auth().getRedirectResult()

[chaitanya4288]

• Operating System version: Windows 10 Pro
• Browser version: Google chrome 87.0.4280.88
• Firebase SDK version: 7.24.0
• Firebase Product: auth

User clicks on social login (with Google) where we call
firebase.auth().signInWithRedirect(provider);

Now user is redirected to google login page, where user enters his credentials.
After successful authentication, he is redirected to our login page where we do the
firebase.auth().getRedirectResult();

Here it is giving an error
{code: "auth/timeout", message: "The operation has timed out.", a: null}

As per the documentation, it says:

Thrown typically if the app domain is not authorized for OAuth operations for your Firebase project. Edit the list of authorized domains from the Firebase console.

But if that is the case then I wonder why it works for most of our users & doesn't for a rare few.

Also, I don't see any api calls in the network tab for this operation.

Thanks for reporting. This -

I wonder why it works for most of our users & doesn't for a rare few.

is my thought too - have you noticed anything in common with these users? We've experienced issues in the past for example that have turned out to be specific to disabled cookie / incognito mode usage.

I got access to one of the user. On his browser, it worked once on normal window and in incognito it always failed.
I didn't find any settings like disabled cookie on his browser. everything was usual.

Hi @chaitanya4288, thanks for the additional info! We are aware of issues with signInWithRedirect in incognito mode, as seen in #3004. For now, we suggest falling back to signInWithPopup and following #3004 for updates.
