It sounds like the Home Hub redirect may be getting stuck rather than the router itself being unreachable. I’d try accessing the hub from a different browser or an incognito/private window first, and temporarily disable any VPN, proxy, or browser extensions.
It’s also worth restarting the Home Hub and checking that your device is connected directly to the home network. If possible, try another device as well. If the hub’s local address still only shows a blank redirect page, clearing the browser cache or trying the router’s local IP address instead of the usual BT address may help.
I’d avoid doing a factory reset until the basic connection and browser checks have been ruled out. For comparison, if other websites such as brickbreaker.io load normally, that would suggest the issue is specifically with the Home Hub interface rather than your internet connection.
