Moved house and LIVE has an issue

So I've moved address and connected my X1 to the wifi. All is good as I can sign in to my proffile, use the internet, netflix etc. But I cannot connect to live and play online.

Anyone know if it's because it's linked to my old IP or something?

if you have previously setup your network manually and if you have a new modem or have reset your modem, it wouldn't work... other than that it can be a firewall issue, but it should be an issue with your network or isp... the accounts work location independent and you can use your correct login e-mail and password to connect to xbl from anywhere...
