Issue

Intermittent error observed with ingest/ retrieve of objects from storageGRID bucket:

Error: reading blob <>: fetching blob: received unexpected HTTP status: 504 Gateway Time-out

From storageGRID Graphana, we observed 504 errors coinciding with 499 errors on the gateway node which matches with the issue observed from application side:

Failed to pull docker image from bucket: Error timed out

Enabled debug level logging
From storageGRID logs, we identified the issue with SSL handshake timeout during upstream of request from the Client to Storage Node via Gateway node:

Gateway node - /var/local/log/nginx-gw/access.log
