Just a quick post to clarify an issue that a few people seem to be experiencing.

A friend of mine has been unable to sign in recently, the launcher tells him that the website couldn't be displayed and to check his Internet settings.

It seems that a few other people are Having this problem too, and as far as I can tell they all have the same ISP (02)

After digging around a bit I found a thread on a different forum where an 02 customer discussed this with their support team and they have clarified that this is an issue in their end and that they are workin on a resolution.

It seems that the only thing to do right now is wait :/
If anyone else knows anything about this then please let me know.
