Hello dear Friends and Cayenne Team.
I used Cayenne to control my Nodemcu Device remote and online, and it was ok,
But now I want use, when I checking Serial Monitor I Faced this error :
 Connected to WiFi  IP: 192.168.52.207  Connecting to mqtt.mydevices.com:1883  MQTT connect failed, error -1
and I tested my PC network and pinging " mqtt.mydevices.com " address, I faced that my network can’t connect to this address! I tested several networks by different ISP but the issue was not fixed.
When I use VPN tunnel on windows, ping is ok, and response!
but I can’t set proxy or VPN on my Arduino or Nodemcu device ! it’s possible? if yes , how ? that set to my codes,
I want give me a solution or :
My device should bypass the tunnel and after this, try to connect to the server and address " mqtt.mydevices.com ", if this can ok, my issue will fix!
