Issue :
Recently i have encountered this error when i was trying to connect to Dynamics CRM 365 online.
I digged in further and found a post where couple of suggestions were mentioned :
https://community.dynamics.com/crm/f/117/t/204264
Solution : It was to do with my system settings(Time) – my system time was ahead of the server time. which means the request was going to server with a future time.
hence i have changed the time in my system clock to be 5 minutes less. Which indeed worked.
I hope this helps!

How did you get the time for D365 online?
I am also facing the same issue

This is very internal to dynamics and most probably your VS/System is the culprit and not dynamics.
So , changing the system time to a few seconds back works.
