It’s likely that the request doesn’t include a compressed transfer syntax in the presentation context. Have you checked the details of the request to see what transfer syntaxes are being negotiated? Could you share a log of the request so we can take a closer look?

“PreferredTransferSyntax”: “1.2.840.10008.1.2.4.50” instead of this if use Use JPEG2000 compression trnasfersunatx will it help
