If you are using Chrome version 56, Chrome v56 and newer block websites using the security certificate SHA1. SHA1 is being fazed out and replaced with SHA2 (this same problem may begin to happen with other browsers, although Explorer appears to be unaffected as yet).  This problem is now occurring in Firefox 51.0.1 and later.  The Library's tech team is working to correct this security certificate problem.

In the meantime, two alternatives may help you to successfully access and utilize Interlibrary Loan:

  • Try using a different browser OR
  • Continue to use the site using a workaround specific to your browser type:

  • Google Chrome v56+:

    1. When presented with the Your connection is not private error message, click the ADVANCED link to the left of the "Back to safety" button

          2. Click on the Proceed to (unsafe) link.

The workaround for Chrome will need to be repeated each time Interlibrary Loan is accessed.

  • Firefox v51.0.1+:

    1. When presented with the Your connection is not secure error message, click the Advanced      button to the right of the blue Go Back button.
    2. Click on the Add Exception... button, which will bring up a popup window.
    3. On the popup window, click the Confirm Security Exception button.

The FireFox workaround should only need to be done once, since Firefox will remember the setting unless you manually change it. 

  • Safari
    • If you are using Safari on a Mac laptop and receive the message “You do not have permission to view this directory or page," or "The website' requires a client certificate. The website requires a certificate to validate your identity. Select the certificate to use when you connect to this website, and then click continue," try a different browser or delete the old interlibrary loan certificate in your Keychain.
    • To delete your old interlibrary loan certificate from Keychain (see How to Solve the Mac Certificate Error Message.pdf attachment for instructions with screenshots):
  1. Click the Finder icon in your tool tray at the bottom of the screen, which looks like a blue and white smiley face.
  2. In Finder, click Applications.
  3. In Applications, click Utilities.
  4. In Utilities, click Keychain Access.
  5. Make sure the bottom category on the left is set to All Items. Look through the lists of certificates under the first three categories under Keychains (login, local items, system) and find any that contain anything related to interlibrary loan, such as ILLiad or  When you locate those certificates, highlight them and hit the Delete key.  When it asks you if you want to delete each certificate, click Yes.  It may also ask for an admin password.  If you don’t have one, just hit Enter.
  6. After closing out of your browser and the Keychain Access, try going back to the interlibrary loan website and see if it will let you login.

The certificate deletion solution for Safari should only need to be done once, because valid new certificates will be stored in Keychain when you login to interlibrary loan after deleting the old ones.
