This issue started around 4 days ago, and it is in relation to opening new notifications.
Most notifications I get are from subscribed links on YouTube. When I clicked on a new notification, I was sent to to YouTube and the relevant subscribed area opened for me to view. Now when I click on a new notification I get this wierd message that comes up.

Hmmm… can't reach this page
Check if there is a typo in 0%7C0%7Cdefault%7C0%7Chttps.

If spelling is correct, try running Windows Network Diagnostics.
