It seems like the issue is with the certificate chain in your keystore. To fix it:

  1. Ensure you’ve imported the CA certificate along with any intermediate certificates into the keystore.
  2. Check that the alias used for the private key matches the alias in the keystore configuration.
  3. Verify your server.xml configuration is correct and points to the proper keystore file.
  4. Restart Tomcat after making changes.

    If this doesn't resolve the issue, you can find a more detailed guide on configuring HTTPS with Tomcat and troubleshooting SSL certificate issues at
