Unable to connect to HTTP Proxy, Or unable to connect to server. Steam Issue and solution!

"Unable to connect to server. Server may be offline or you may not be connected to the internet."

I have had an issue where both my steam client and my operating system did not allow me to access my inventory, nor any other users inventories. I searched for a solution and found it.
