Invalid port number:

Error message

Invalid port number: 

What it means

Port validation in parseDriverUrl: the URI parsed from the JDBC URL contains a port outside the valid range (less than 1 or greater than 65535). The offending URL is appended; this catches mistyped ports like 0, negative values, or values overflows.

Solutions

1. Use a valid port number (1-65535) in the JDBC URL
2. Verify against the coordinator's actual configured port
