Error WIS 000509

Hello

I've installed BO v11.5 release 3.0 and have come across the following error after setting everything up

The Universe data connection could not be found. The connection has been deleted or you don't have the right to use it. (WIS 000509)..

The connection does exist, I can see it in the administrator panel and in the designer. The connection in the designer connects successfully to the database (verified using the "Test" button) but when I go to "Refresh Data" from Infoview for a specific query, I get the error above. This has been installed the same way on 4 machines and this is the only one with this issue. TIA
