I am simply trying to send a simple HTTP request from an Arduino Uno with w5500 Ethernet Shield to a local server running on my PC.
The two are connected via a crossover ethernet cable and I am able to host a server on the Arduino that is accessible from my PC browser. Now I am trying to use the PC as a server and the Arduino as the client.
Using the simple WebClient example, I can send a successful GET request to google.com from the Arduino.
Here is what I am trying that is failing:
1 - Start a local server via running http-server in my command prompt. That successfully starts a server at 192.168.56.1:8080 that I can access via my browser
2 - Change the Web Client example to use
and change the port to
if (client.connect(server, 8080))
3 - Run this Arduino sketch. The connection fails and I don't know why. I have allowed port 8080 full input access through the Windows firewall.
