Cannot connect to CC Server

Hi, So i'm on windows 10, had this laptop about 3 months, it's been running CC with PS, AE and PP fine, until last week when suddenly it had problems signing in to CC. I needed to install Audition for an animation soundtrack.

I've tried on 2 different internet connections, I've disabled and eventually un-installed my internet security, disabled windows firewall.

Also 3 other laptops have been able to connect with CC desktop app on the same internet connections.

But the message i receive says that it cannot connect to the server and to please check my computers clock is correct as well as any firewall settings.

I've already tried using the utility to uninstall all the Adobe programs and use the CC Cleaner to clean all traces. I think one of the remote desktop sessions I had also cleaned out the other few leftover files.

I don't understand what might have happened to suddenly create a problem, I don't really want to have to completely wipe my laptop to resolve this and it seems none of the adobe support team are able to find out what might have caused this problem, so any help would be really really appreciated.

It would be great to have a utility that checks the connection to the adobe servers outside of the CC desktop application, if only to prove to support that that's not the issue.

As i said i'm running up to date windows 10, on a Dell laptop with 8gb and intel i7, the internet connections i've tried are from 10 to 50/60 mbps in speed.
