Starting with version 1.10.11 of the player, if a user attempts to playback a session from the activity center of the SPP user interface, the player will launch, prompt the user to continue or abort if the SSL certificate is untrusted and then fail to playback the session.
This happens if the default SSL certificate is still being used by SPP and the certificate has not been installed on the user’s client computer as a trusted certificate. It could still happen if the admin has installed their own SSL cert chain and the cert chain has not been installed on the user’s client computer as a trusted certificate chain. The problem was introduced by an upgrade to the QT library in the Desktop player.
Workaround: The workaround for this issue is to either not use the latest version of the Desktop player or install the SSL certificate on the user’s computer. If you install their own SSL certificate chain in SPP that may allow you to continue to play back the session even if the SSL certificate is untrusted, but that is not guaranteed to fix this.
The only way to make sure that the Desktop Player won’t fail due to an untrusted SSL certificate is to install the SSL certificate chain on the user’s computer. Keep in mind that the latest version of the Desktop player will fail even if the user clicked on the continue button after being warned that the SSL certificate is untrusted.
