Are you running into those pesky 401 error codes trying to log in to or navigate around in the LunaDNA platform? Below is one of the most common causes we've run across and a fix!

Your computer's system clock is out of sync with reality

You might never even realize it until you start logging into websites that have a security rule in place that restricts the actual time it takes to complete your log in. This security protocol helps prevent malicious attacks that can put your account at risk. If your computer's clock is out of sync, we can't be sure the true time it took to complete your log in attempt. Mac computers have a built in mechanism to warn you about this and guide you to correcting it before letting you use a web browser. Windows computers are not as straight forward. Here are the steps you can take to re-sync your computer's clock if you are using Microsoft Windows:

  • Go to your Control Panel (if you don't know how to get here, type "control panel" into your search box in the start menu).
  • Click to open the Windows Control Panel.
  • Scroll or use the search tool to find the "Date & Time" setting. Click to open it.
  • Click the "Internet Time" tab and click "Change Settings".
  • Check the box that says "Synchronize with an internet time server" if you wish to automatically sync the clock. (See this link for more information.)
  • If you want to sync the clock, select a server from the dropdown menu to sync with or type in the address of one you prefer (such as if there is one on your network).
  • Click "Update Now" to immediately sync the clock and verify the settings work.
  • When you're done verifying, click "Ok".

For additional details, and if for some reason you need to manually do this for a Mac, please review this link.

If you are running a computer with Windows 10, the steps are a little different:

  •  Press Windows key + "r" (the window key is the rectangle with 4 smaller rectangles in it)
  • Type: "services.msc"
  • Click "Windows Time" in the "Name" column
  • Alternate click and then click "Properties"
  • Change "Startup type" to "Automatic" (if it is not already set to "Automatic")
  • Click "Start" if the service isn't started
