@KayleeSC do we need any extra setup or changes in the iOS app for using OHTTP relay while using it in development or testflight , currently I using sample app from https://developer.apple.com/documentation/networkextension/filtering-traffic-by-url. Because I setup both OHTTP gateway and PIR server on my local but I can not access PIR server getting logs on the OHTTP gateway . DEBUG request{method=POST uri=/config version=HTTP/1.1}: tower_http::response: finished processing request status=400
