Google Social Login - Error 403: disallowed_useragent

[partners]

Hi everyone,

There are couple of topics for that error on Community, but none of them have the solution posted, so I decided to create a new topic.

We integrated Google Login(Plug and Play kit) to our Unity-based mobile game, and things were going fine, but in our cross-device testing, we started to see the Error 403: disallowed_useragent

I attached the screenshot for this error page.

We also did some testing on Emulator, and tried to switch with multiple useragents, but seems like the issue with the link itself rather than the device/user-agent.

Here’s the link we get for the Google Social Login, and we tested this link from multiple locations/device, and getting the same 403 Errror.

Please kindly let us know how to fix that error.

Thanks in advance!

@partners Thanks for your recent post.

I think this is an issue with your emulator and the fact that it’s launching the authentication session in WebView Browser Tester app and not an installed browser application (ex. Chrome). If the play store is installed on the emulator, download chrome and set this as the default browser.
