Sky sports on web browser - an unknown error has occurred, wholesale error

On chrome on my laptop I tried logging into Sky Sports via Virgin Media login page. From the sky sports page, I click login 'Virgin Media UK sign in', and then I am brought to a page that says "There was an unexpected error" (addr: skyid.sky.com/error/wholesaleerror). Incognito mode on Chrome does not work, and neither does Safari. 

I have tried clearing the cache and all cookies for sky sports but nothing seems to work. Chrome is up to date. Others seem to have had a similar problem and for some the fix just happened out of the blue, but none have worked for me.

I have a screenshot of the page that comes up when I try to login

Any help would be greatly appreciated.
