Original GitHub issue: https://github.com/ProxymanApp/atlantis/issues/159

I passed shouldCaptureWebSocketTraffic:YES

 [Atlantis startWithHostName:@"192.168.100.46" shouldCaptureWebSocketTraffic:YES];

Here the code that create mqtt connection

#include <mqtt/async_client.h>

// ...

mqttClient = make_shared<::mqtt::async_client>(uri, clientId, opt); // uri: `wss://avusnlsslh8sx-ats.iot.us-west-2.amazonaws.com`

connOpts = ::mqtt::connect_options::v5_ws();
connOpts.set_http_headers(std::move(headers)); // aws headers

::mqtt::ssl_options sslOpt;
sslOpt.set_enable_server_cert_auth(false);
connOpts.set_ssl(std::move(sslOpt));

mqttClient->connect(connOpts, nullptr, *this);

I also tried to add proxy manually, didn't help :(

        connOpts = ::mqtt::connect_options::v5_ws();
        connOpts.set_http_proxy("http://192.168.100.46:9090");
        connOpts.set_https_proxy("http://192.168.100.46:9090");

@retyui Atlantis can only capture websocket if it's called by using URLSessionWebSocketTask.

Atlantis can't work with mqtt.

I suggest using a normal proxy with Proxyman (not using Atlantis) and setting an HTTP(S) Proxy to Proxyman as you've already done.

Follow this doc for iOS device, or iOS Simulator
