Body
Environment
- Many websites, including some U-M sites
- Older web browsers and operating systems including, but not limited to:
- Safari, Firefox, Chrome, and Opera
- MacOS 10.12 and below
- Windows XP
- iOS 10
- Older versions of Android
Issue
Older browsers may report certificate / security errors when trying to access websites (including at U-M), because the browsers lack the ability to verify some newer security certificates. In this case, the browser may report a problem with the website, although the issue is more accurately a limitation with the browser, or the operating system running the browser.
Example errors:
- Can't verify identity of website, Continue?
- This website may not be secure, Continue?
- Your connection is not private
- Your connection is not secure
Resolution
For MacOS 10.11.x (and older)
- Download the new root certificate - either here: https://crt.sh/?d=1199354 or attached to this knowledge article (usertrust-2038.crt)
- Click the downloaded file to launch Keychain Access
- Click 'OK' to continue through the warning menu that pops up as the Mac Keychain Access tool starts
- Select the keychain 'System' from the dropdown.
- Hit 'OK'
- Click 'Always Trust' on the window
- Restart the computer
For MacOS systems when the above steps do not work

- If still experiencing trouble, update to a recent version of the operating system (MacOS, Windows, iOS, Android), then try step 1 again
Windows and other non-Mac systems
- Update to the newest version of Firefox or Chrome that will run on the device
- If still experiencing trouble, update to a recent version of the operating system (Windows, iOS, Android), then try step 1 again
