+#### Force OpenAI upstream HTTP/SSE
+
+When an egress proxy or network repeatedly reconnects OpenAI Responses
+WebSockets, set the global fallback in the persisted deployment configuration:
+
+```yaml
+gateway:
+  openai_ws:
+    force_http: true

+For Compose and Apple container deployments, the equivalent `.env` setting is:
+
+```bash

+This selects HTTP/SSE for OpenAI upstream Responses traffic that would
+otherwise use WebSocket. It does not change the client-facing protocol or force
+HTTP/1.1; configure `gateway.openai_http2.enabled` (or
+`GATEWAY_OPENAI_HTTP2_ENABLED=false`) separately when a proxy is incompatible
+with HTTP/2. Unlike the account-level `http_bridge` mode, this global fallback
+takes effect without enabling `mode_router_v2_enabled`. Keep the setting in the
+deployment's persisted `.env` or `config.yaml`, rather than inside a running
+container, so it is read again after an image update or container recreation.

 The initial admin account is **only created via the setup wizard** (served at `http://<host>:8080` on first run). The `default.admin_email` / `default.admin_password` fields in `config.yaml` are **not used** to create it — they exist in the template for historical reasons.
