Service Trust Portal - Downloading Documents throws an "Internal Server Error"

Since the same internal server error appears in both STP classic and v2, this looks like a tenant/account access path issue in the document delivery backend, not only a local browser glitch.

1. Confirm you are signed into the correct tenant and that your account has permissions to access those compliance reports.
2. Reproduce once in InPrivate mode and once with another supported browser to remove cookie/session interference.
3. Test with another authorized admin account in the same tenant to see whether issue is user-specific or tenant-wide.
4. Capture UTC timestamp, report name, correlation/request IDs, and full error screenshot from both portal versions.
5. Open support with those diagnostics and request backend trace for STP document retrieval failures.

Validation checks:

• Target documents download successfully for at least one authorized account.
• No Internal Server Error in both classic and v2 experiences.
