- you might potentially be using the wrong IP address, but one that happens to be associated with an existing host
- your host might potentially have a firewall set up that is blocking outgoing connections to that host or that port
- the receiving host might not have anything configured for port 50000 and so is refusing connection to that port
- the receiving host might potentially have a firewall configuration that is blocking your access to the port

I have an Arduino Ethernet Shield R3 with an Arduino Uno R3. Any idea if I can use this to connect to ThingSpeak with this? And also I can't seem to get the example https://www.mathworks.com/help/supportpkg/arduino/ref/using-ethernet-shield-with-arduino-hardware.html working. For Task 2, I can send but i keep getting error for receive.

ThingSpeak should be agnostic of the hardware used for conenction, as long at is supports http or MQTT.
