Error testing hue connection during services setup in CDP Private Trial: Unexpected error. Unable to verify database connection

Riyadbank — Tue, 21 Apr 2026 06:22:45 GMT

I get

"Unexpected error. Unable to verify database connection"

I checked cloudera-scm-server.log file, found the following ERROR:
