So i have a webserver in the local network that can be access through 192.168.1.5:8080 As you can see in this picture of the terminal
I can confirm that this is running because when i go to a browser and type the address i am seeing the webpage.
So am using the Ethernet webclient example. to test things out. just as is without modifications it was able to connect to google.com no problem. but when i try to change the address to 192.168.1.5, it says connection failed.
/*
Web client
This sketch connects to a website (http://www.google.com)
using an Arduino Wiznet Ethernet shield.
