Don’t worry- this issue is easy to fix.  It usually happens when your system time or time zone is incorrect, or if the time on your PC has been changed frequently
To set your time and time zone in Windows 10/11, go to Start>Settings>Time & Language> Date & Time. Enable the two options: Set time automatically and Set time zone automatically.
For macOS users, go to Apple menu > System Preferences> Date & Time. And click on Time Zone and turn on Set Time Zone automatically using your current location.
