Using Arduino Programming Questions
1

I am getting this error after uploading my sketch to ESP 8266, while trying to connect.

ArduinoIoTCloudTCP::handle_ConnectMqttBroker could not connect to mqtts-up.iot.arduino.cc:8884
ArduinoIoTCloudTCP::handle_ConnectMqttBroker 1 connection attempt at tick time 11396

Any helps is much appreciated in advance.
