Flush your DNS (Mac OS)

On MAC OS and Go-Global there is sometimes an issue with MAC OS caching old DNS records.

The DNS Cache is essentially a piece of data that stores a bunch of web addresses for quick access in the future. Your computer will check this before trying to connect.

You can wipe it by going to Applications -> Utilities -> Terminal 

Copy the following command and press enter. You may be prompted for your password.

Please wait a few minutes, then restart your computer and then try and connect.
