Thanks for posting your question in the Microsoft Q&A forum.
Here are some troubleshooting steps you can try:
- Double-check that the
CodeSigningAccountName
andCertificateProfileName
values in your metadata.json file are correct and match your Trusted Signing account and certificate profile. ensure that you have the necessary permissions (Trusted Signing Certificate Profile Signer
role) assigned to your account or group for the specified certificate profile. - Confirm that the publisher name in the AppxManifest.xml file of your MSIX package matches the subject name of your Trusted Signing certificate profile exactly. any mismatch in the publisher name can cause the Trusted Signing service to deny the request.
- Check if the
Endpoint
value in your metadata.json file is correct and matches the region where your Trusted Signing account is located.
