What router do you have?
There are a couple of things you can try that could clear this. There are other things to try if these don't work.
Try turning off your router for 30 minutes then restarting. This will force a new session.
If this does not work, you could try using a different, public DNS server like Google's (8.8.8.8 and 8.8.4.4). You can change this within you router dashboard.
Please let us know how you get on.
