CC Libraries not syncing

[Tabrez]

Hi there,

I've created a few new libraries and just started experimenting with the sync feature. However, it always fails to sync. I've signed out and signed in again, that didn't help. I've also tried following the instructions on this page and nothing worked: https://helpx.adobe.com/x-productkb/global/creative-cloud-crash-core-sync.html

Attached is a screen shot of the error I'm getting.

Many thanks!
