+#### `CONDUCTOR_HTTP2_AUTO_FALLBACK`
+
+- **What it does**: When HTTP/2 is enabled, a protocol-level error (e.g. `httpcore.RemoteProtocolError: <ConnectionTerminated ...>`) triggers a one-time, one-way automatic fallback to HTTP/1.1 for the remainder of the process.
+- **Default**: `true` (auto-fallback enabled).
+- **Values**: `false|0|no|off` keeps retrying on HTTP/2 instead of falling back. Anything else keeps it enabled.

+```shell
+export CONDUCTOR_HTTP2_AUTO_FALLBACK=false
