mqtt message loss

Alexandre | Last updated: Sep 15, 2022 08:06AM UTC

Hello, I use Burp Suite Pro 2022.8.4 to intercept MQTT over Websocket. Broker sends "restart" command, the client sends "reply" and closes the connection. Burp often fails to intercept and relay that "reply" message. I have tested the same with mitmproxy and have no issues there. Best regards, Alex
