SSL is a security technology for transmitting sensitive information like passwords and credit card numbers. Some of the systems we use in UK Libraries, e.g., EZProxy, take advantage of SSL. Part of the SSL process includes a certification, which is periodically renewed. If a certification has changed, you may see a warning message like this:
Depending on your browser, the message may say something like "Connection is untrusted" or "There's a problem with the website's security" or "Certificate is expired" and the error message will include the site URL, e.g., ezproxy.uky.edu. If you recognize the URL, as you would with EZProxy, you can click through the error message and temporarily ignore the error. But you'll continue to see this error each time you access the site.
There are steps you can take to update your browser so it recognizes the new certificate. NC State Libraries have provided a helpful page with information on the steps to take to update a variety of browsers. Follow the steps provided for your browser to update with the new ipsCA certificate.
