Hi @Ragunathan46

can you show the error message in “Event Viewer”?

EventViewer => Windows Logs => Application => There should be an error message with a “red error sign” in column “Level”. Can you please post the message?

I used Windows authentication while installing Uipath test manager


Thanks. Looks like your user cannot access SQL DB.

Any chance to test the SQL DB User?

Please try SSMS and login directly to SQL DB with given credentials. Then we can check oft this works.

You can get it here: Download SQL Server Management Studio (SSMS) - SQL Server Management Studio (SSMS) | Microsoft Docs

Same user I used for installation and uipath test manager database created successfully.
same server used for Orchestrator and Orchestrator database also same server.
Uipath Orchestrator working as expected.

I am using Windows authentication for all installation like Orchestrator and Uipath test manager

Issue fixed, In application pool identy changed default to domain/username.
