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