I got the same problem.

[arijeetbaruah]

min Version API level: Andriod 9.0
target API level: Highest installed (SDK 30)

In my case

[moldovev]

In my case the problem was that I had Anti-Piracy Enabled.

To turn it off go to Google Play Console
Select app -> Play Games Services -> Setup and Management -> Configuration -> Credentials (Android) -> Edit -> Enable anti- piracy OFF

[chico-barnstorm]

We've been experiencing the same recently, for a few days too - in our case it does happen for [new apps pointing to new Google Cloud projects] as well as [new apps pointing to existing and fully working Google Cloud projects].

We've checked many, many times our setup and all looks fine: credentials/SHA1 fingerprints for the Upload and App signing key certificates, testers, tracks and Google Cloud setup. All absolutely fine. Yet we keep getting the confusing "error 16".

• We're using Unity2018.4.32f1, with the latest version of the plugin (0.10.12).
• Min API Level: 16
• Target API Level: 30 (Highest Installed)
• No Anti-Piracy enabled

GooglePlayGames/BasicApi/CommonStatusCodes.cs

The result was canceled either due to client disconnect or cancel().

Canceled = 16,
If there's no logic to auto trip cancel and network is not faulty, then I'd look at where the call is made. Calling leaderboard from inside a callback can be problematic.

[cometa93]

We have the same problems,
we are also using "EnableSavedGames"

[payini]

I get the same error.

[sanook8899]

I get the same error.

Do you fix it?

[sicklydove]

We are also experiencing this, will update if I find a fix.

[quanarmy]

Same problem :(

Alright, so this cost me about two full days of dev time.

In the end, it was because the OAuth consent screen had User type set to 'Internal', and the Google account I was using for testing was not managed by the company in question. For small organisations I think it's generally easiest to always use 'External' here, and just add email addresses for testing/development - especially if using contractors.

Anyway, after lots of back-and-forth I found the best way to debug it was with the Android monitor which can be found in the tools directory of your JDK. The native SDK writes a lot of extra logging information here, which unfortunately doesn't reach Unity. Once you have monitor running, and your device attached, try filtering the logs for Errors, or with the query tag:PlayGames. In my case, it did actually point me in the right direction.

It should look a bit like this.

Here are some of the other things I learned along the way, in the hope they help someone else:

• This response is a very generic 'catch-all' that covers a large number of possible error cases, several of which are misconfiguration. This is particularly unhelpful, as 'cancelled' would, to me, imply a fairly specific situation. Apparently not, oh well.
• If you are building straight from Unity and loading onto a device via USB cable, make sure that the fingerprint of the attached Android Credential in the Google Play Console is the SHA-1 fingerprint of the local keystore you are using to build in unity. do not make a development build; this will be signed with a different keystore. In the Google Play Console, this fingerprint should be the same as that of your 'Upload key certificate' listed on App Integrity.
• You can double-check that the fingerprint of the .apk matches that of the Upload key certificate by unzipping the apk, and running the following command keytool -printcert -file /path/to/unzipped/apk/META-INF/CERT.RSA
• If you are building from Unity, uploading the apk to Google Play Services, and then downloading the APK from the Play store onto your phone, the SHA-1 fingerprint of the attached credential should not be that of of your local keystore, instead, it should be the fingerprint of the 'App signing key certificate' listed in App Integrity. This is because Google Re-signs your app with their own key stored on their servers, before pushing it up to Google Play.
• Make sure that the Google Play Games user you are attempting to log in with is listed as a Test User in your OAuth consent screen, as well as in the Console.

I'm facing this problem yet...

[bcmccracken]

Thank you @sicklydove, your tips were very helpful! I noticed that monitor is officially deprecated in Android Studio 3.1 and being removed from Android Studio 3.2, but adb logcat will provide similar results. My problem is that I was formerly running adb logcat -s Unity to filter those down to Unity logs, but most of the useful logs aren't Unity, and many of them also don't have the PlayGames tag mentioned. PlayerAgent was the tag for the log entry that was most useful to me, pictured here:

I hadn't yet published my Play Games Configuration in the Play Games Console, as it warned that some changes to the game wouldn't be possible after publishing, and leaderboards and achievements couldn't be deleted. But that was my issue--the configuration couldn't be found, and that was causing the auth issue.

[kuoliangkwong]

I had the same issue but managed to fix it by adding my testing account in Play console.

It was still throwing error after adding the account until I cleared app data for Play Store, Play Services, Play Games apps.
