Version

Doris version: 3.0.3

What's Wrong?

When using the LOAD LABEL statement to ingest data from an S3-compatible object store via HTTPS, the operation fails with a "connection refused" error in Doris version 3.0.3. The same configuration and credentials work perfectly in version 2.1.8, indicating that the issue is likely specific to the 3.x.x series and its handling of HTTPS.

Observed Behavior:

BROKER LOAD works as expected in Doris 2.1.8 with HTTPS S3 endpoint.

The same load command in Doris 3.0.3 returns:

ERROR 1105 (HY000): errCode = 202, detailMessage = Failed to access object storage, message=Connection refused

Other operations using the same endpoint and credentials (e.g., SELECT FROM S3, CREATE STORAGE VAULT) succeed in both versions.

Possible Root Cause:
Doris 3.x.x may have introduced changes to its object storage access mechanism that breaks or disables support for HTTPS connections during data load operations.

What You Expected?

HTTPS S3 endpoints should work consistently across Doris versions for all S3-related operations, including LOAD LABEL.
