Background:
On systems using a proxy server, some browsers can experience issues displaying local webpages, those hosted on the same system.

Solution:
This can be fixed by disabling the proxy for local webpages, those hosted on the same system as where the browser is running.  You can do so using these steps:

Windows:
-    Open the Control Panel
-    Open the Category “Network and Internet”
-    Click “Internet options”
-    Open the Connections tab
-    Click the “LAN settings” button
-    Enable the “Bypass proxy server for local addresses” checkmark
-    Click OK
-    Click OK

































Mac:
-    Open System preferences
-    Open the Category “Network”
-    Select the Connection you are connected to the internet with (Ethernet or Wi-Fi)
-    Click the “Advanced…” button
-    Open the “Proxies” tab
-    Add localhost and 127.0.0.1 to the comma separated list of hosts to ignore
