Unable to use SSE-C with MinIO behind a reverse proxy

[sanjaysrikakulam]

Hi,

I deployed an MinIO instance via EGI for testing SSE-C and I get the following error

mc: <ERROR> unable to upload. Requests specifying Server Side Encryption with Customer provided keys must be made over a secure connection.

Deployment info:
MinIO release: RELEASE.2024-10-02T08-27-28Z

Debug message:

Cmd:

mc put --enc-c "ssecminio/ssec-test/enc_test_file=XXXXXXXXXXXXXXXXXXXX" enc_test_file ssecminio/ssec-test/enc_test_file --debug

Relevant issue: minio/minio#6093

Having the SSE-C, SSE-KMS, and SSE-S3 will be great for secured data analysis.
