When a security warning appears (Android)

If you're browsing a library's digital collection and you get a security warning message, your device is not making a direct connection to the authentic OverDrive service. Instead, a third party is intercepting your connection to OverDrive. Security warning messages include:

  • "There is a problem with the security certificate for this site."
  • "Hostname mismatch"
  • "The certificate authority is not trusted."
  • "This certificate is not from a trusted authority."

This warning is often triggered when a public Wi-Fi provider prompts you to sign into their service. In these cases, you should be able to resolve the warning using these steps:

  1. Open a web browser on your device and go to http://example.com (make sure you're using http, not https).
    Note: Example.com is a website reserved by the Internet Assigned Numbers Authority (iana) for use in documentation. Many websites forcibly load with https, but this site is accessible with http.
  2. You should see a sign-in prompt from the Wi-Fi provider. Sign in if you'd like to use their service.
  3. Close and then reopen the app or website where you initially saw the warning.

After following these steps, you should no longer see the security warning in your digital library.

If you still see the warning, or if you couldn't complete these steps because you didn't see a sign-in prompt, we recommend that you contact the provider of your internet connection to determine whether this is an official part of their service. If you continue despite the warning, the third party will have access to the information you send and receive, possibly including passwords, reading activity, and other private or personally identifiable information.
