401 Unauthorized error when calling https://api.risk.lseg.com/screening/v3/cases?screen=SYNC

Nihal

Dear LSEG Team,

I'm encountering a persistent 401 Unauthorized error when calling https://api.risk.lseg.com/screening/v3/cases?screen=SYNC from my Java application.

Notably, the API works fine when tested directly within the WC1 environment. However, the same request (or equivalent cURL generated) consistently returns a 401 when made as a new request from my development setup.

I've already verified the API credentials, groupId, and system time synchronization.

Attached are the cURL command for your review.

Please advise on a resolution.
