"Server not responding" error message in Communication Service resource

Question

I attached a picture of what I see on my end. This message always comes up whenever I try to click on any option on the side menu inside of my communication service resource. When I click on "phone numbers," "direct routing," and "short codes," on the side menu, I get this error message. See attached picture.

"We were able to determine that the issue was caused by the local time on your computer being set to a future date time. This datetime was being passed in the HTTP header and thus causing a validation error. After resolving your computer time sync issues, you were able to request phone numbers from the service. "
