– Certificate errors are typically caused by an incorrect date or time in your operating system’s calendar.

To set your Date and Time Properties in Windows, please follow these steps:

  1. Double-click the time in your taskbar to open the Date & Time Properties menu.
  2. From the Date & Time tab, verify that the appropriate month, day, and year are selected.
  3. Click Apply to save any changes you make.
  4. From the Time Zone tab, verify that your time zone is selected. If the time zone in which you are located is not displayed, select your time zone from the drop-down menu.
  5. Verify that the box beside Automatically adjust clock for daylight savings changes is checked.
  6. Click OK.
  7. Close all your browser windows, restart your browser and try logging in again.
