Unhandled exception communicating with MQTT Broker #4

Open hajeth opened 8 months ago

hajeth commented 8 months ago

I built a WLED project with an ESP32 Wroom 32 Device and Wled is using this TCPAsync Library. After some time (Seconds to Minutes) the ESP32 reboots. Debug log shows many events with no Argument handled by AsyncTCP library then it crashes. When this happens, packet traces do not show any network traffic to the ESP32.

Log:

I tried different ESP32 devices, different WLAN APs and different MQTT Brokers - all with the same error.
