Select the certificate. It is most likely you will need to add the .key file (with password) and the certificate itself.
So you will likely need to add the use password format unless a PKS12 certificate (has both key and cert) is installed, if so, select that checkbox.

If you wish to just use the default Extreme Certificate, select Generate Certificate. Keep in mind, this is not a well know certificate to operating systems.
If the validate certificate is used on the operating system, the authentication will likely fail. However, if it was used in the past and expired, you can use the generate certificate to replace the local certificate with an updated one.
