MQTT in Plugin disconnects frequently
This all points to the direction that the underlying JS-Engine in the Streamdeck software might throttle the outgoing connections. I still don't understand what's under the hood. The user agent returns "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/6.3.1 Chrome/94.0.4606.126 Safari/537.36" What's the JS Engine in the Software? Is it Chrome? As far as I know, there are some issues with Websocket disconnects in Chrome due to aggressive throttling of background tabs. Could that be the cause here, too? https://github.com/mqttjs/MQTT.js/issues/1268
