Did your ip address change?

It should not of have it is still sending info to portal

That doesn't mean your ip address have not changed.

How would it change? also how do I find out?

Your router did it.
Check on the router list of connected devices.
If the wifi attachment hasn't changed, you are probably using the external ip address that is controlled by your internet provider.
You can choose to get a static ip address. Call them to see how much more it would be. Or try one of the DDNS services available out there.
