# NousResearch/hermes-agent · SSE keepalive during preflight compression phase

## Open now

- Nothing open on GitHub.

These items address SSE connections dropping or timing out on remote clients when the API server or gateway performs preflight compression without emitting bytes. Fixes involve keeping SSE streams active through that silent period.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
