Can you get to the site without the VPN?

I can get it without VPN but I get 'Not available in your country' hence use of VPN

Doesn't sound like a browser issue.

Some websites that have restricted content are able to check your actual location and how you access their server. If they suspect that you use a VPN or proxy due to the IP range (i.e. your IP does not belong to a known ISP) then they might block you because you violate their policy.

Browser is fine otherwise, could they have some form of VPN alert or something they do not use but the browser wants?

I have an account, paid in the UK and using London on VPN. Used OK almost daily until the last 'partial' update

Now working again. Thanks guys!!!

Maybe you were using a server that didn't support that website properly and now switched to a different server that works better.
