Lenses can be placed behind a proxy, but you must allow websocket connections.
These two paths are used for WebSocket connections:
/api/ws
/api/kafka/ws
Disable proxy buffering for SSE (Server Sent Events) connections on this path:
/api/sse
Lenses supports TLS termination out of the box, see Enabling TLS
