Troubleshooting

Check that your connection definition references your JDBC database with
correct URL syntax, username, and password. The authentication type 10 is
not supported.

When connecting to Timescale with a Java Database Connectivity (JDBC) driver, you might get this error message.

Your Timescale authentication type doesn't match your JDBC driver's supported authentication types. The recommended approach is to upgrade your JDBC driver to a version that supports scram-sha-256 encryption. If that isn't an option, you can change the authentication type for your Timescale service to md5. Note that md5 is less secure, and is provided solely for compatibility with older clients.

For information on changing your authentication type, see the documentation on resetting your service password.
