## What this error means

Google Play expects uploads signed with the app’s registered upload key. This bundle was signed with a different keystore.

## Why it happens

Play has an upload key on file for this package. The bundle was signed with a different certificate, so the fingerprints do not match.

## The message tools print

```
Google Api Error: Invalid request - Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again.
```

## How to fix it

1. Sign with the original upload keystore — compare its SHA-1 fingerprint with the one in the error.
2. If that key is lost, ask for an upload key reset on Play Console’s App integrity page, then sign with the new key.
