XF 2.0 Google Oath 2.0 Integration with subdomain

[bonarongrong]

I have created Google Apps as what have been said in
https://xenforo.com/xf2-docs/manual/connected-accounts/
So I tried and got error like this

Error: redirect_uri_mismatch
The redirect URI in the request, http://forum.domain.com/connected_account.php, does not match the ones authorized for the OAuth client. To update the authorized redirect URIs, visit: https://console.developers.google.com/apis/credentials/xxxxxxxx

I think this because the authorized domain is domain.com, not the subdomain
And when i enter the subdomain, it asked TLD only.

So any advice?
