* Sandblast agent is configured to send files for emulation to cloud, download several files would succeed.

## Cause

The main issue here is that a file that takes long for TEX to process, causes subsequent files to fail. As a result, the Endpoint agent would reject this connection as timeout is "10 seconds"..

Infrastructure does not handle correctly multitude of requests from the same client. On the other hand, requests from different users can work simultaneously just fine.

Root cause is that requests from the same client are done on the same connection.
