Some browsers and devices store website location data in your system for quicker access with the DNS Cache.

If your DNS cache contains geo-blocked versions of the websites you are trying to access, your device will not use Web Connect to get past those blocks and you will continue to be directed to the geo-blocked page. 

DNS Cache needs to be flushed if you are having trouble getting past geo-blocks.
