Have you tried switching the router off for over 30 minutes, then when you switch it back on it will start a new 'session' in the street cabinet, this can sometimes help resolve issues where certain random websites can't be accessed.
Yes tried that well but nothing. Called talk talk and they said you have an old router and will send a new one, thought that was quiet funny as I only joined talk talk about 2 weeks ago and they sent me an old type router. It worked fine before with BT n Sky.
if new router doesn’t sort then I will be asking them to opt out of my contract as I need this site to work from home.
