HTTPS 400 = Bad Request. See: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/400

There can be multiple reasons for this, the below are not a full description of all potential root causes but describe some of the reasons for this error:

  • Auth rejection due to SSL: try unchecking SSL
  • Credentials: have customer double confirm credentials inputted in to Looker connection settings
  • Malformed DB hostname or other parameters: are there any whitespaces in the db hostname or in additional params? This will be hard to determine from the UI but the JDBC string or logs should make this more apparent
