Error: NetConnection.Connect.Failed

[From the other posts, don’t know if this is abandonware or if it’s actively supported, but over the next week we’re evaluating plugins for a recruiting company’s video interview page, so a timely response would be appreciated.] Attempting to insert shortcode inline in HTML text editor for your accompanying plugin Video Posts Webcam Recorder, from the the Recorder tab, like so: [videowhisper_recorder height=”550px”] However, on the video interview page, though the video recorder and playback windows are visible, the following error displays on top of them: NetConnection.Connect.Failed I appreciate the robustness of the plugin’s back end, but we had previously used Vidrack (recently deprecated with new site theme), and it was very easy to manage with posting the videos within the site’s WP automatically. I’m guessing the above issue is a problem with the video server setup, but your I/O is somewhat dense. Would appreciate any assist with making the connection. Also, we just tested Pipe Video, which worked intuitively out of the box, we’re just trying to see if we can make even your ad-supported player work, and we’re possibly interested in the lifetime license. Thanks in advance for your help. https://wordpress.org/plugins/video-posts-webcam-recorder/
