My BT Smart Hub is no longer updating DDNS with changeip.com. It used to work fine until recently. Is it working for anyone else? Known problem?
I first saw the problem after a power-cycle of the router and - I guess - a new external IP address. I don't known when the DDNS service last worked (I wouldn't notice unless the IP address changed).
When I check the admin interface I see "Service status: Error". Refreshing the page doesn't fix it, restarting the router doesn't fix it, power-cycling the router doesn't fix it. I can't see anything of relevance in the logs.
I've confirmed my credentials on changeip.com on both the web interface and by calling the DDNS API directly. I also recreated the changeip.com settings on the router with a new password and that still failed.
