Many people seem to be having issues with accessing certain websites using TPG Internet service provider. For those who don't know, TPG uses an intercepting proxy (also known as a "transparent proxy") which means if you do not specify a specific proxy server in your browser, they have a default proxy which will be used.

You can find out which proxy is being used for your Internet connection by going here.

To fix this issue, you can nominate a specific proxy server from a list of TPG proxies to be used rather than letting TPG picks a random one.

However, just to be absolutely sure that it is the TPG proxy that is causing these issues, access the websites using a web proxy to see if the same problem occurs. If the problem cannot be replicated using a web proxy, it is definitely the ISP proxy issue.

How to specify a proxy server

In Internet Explorer:

Tools -> Internet Options
In Connections tab, click on LAN settings
Tick 'Use a proxy server' and add the proxy address you want to use (eg: proxy.tpgi.com.au) in Address field as seen below

Click OK
Click OK

In Firefox

Tools -> Options
Click on Advanced icon from the toolbar
Click on Network tab
Click on Settings
Select 'Manual Proxy Configuration:'
And enter the proxy address you want to use (eg: proxy.tpgi.com.au) (see below)

Click OK
Click OK

You might have to wait for 5-10 mins for your browser cache to be refreshed or you can manually clear the cache.
