Recently upgraded to Fibre and when the connection is connected, it is fast, so this is good.
However seemingly randomly Chrome will not let me connect to standard sites like google or amazon etc and shows me a 'your connection is not secure' error message and will not let me proceed for a minute or so.
(on two different computers this has happened)
Sometimes on refresh it then shows a talktalk error message for not being connected to the internet at all, but then a minute or so later it will be fine.
Any advice?
