[Plugin: BuddyPress Media Component] New Install: "Unable to Connect Media Host Server!"

I am using latest WP, latest BP, latest Kaltura, and just created a new Kaltura account for the first time. In WP, in the plugin’s settings under BP, I put in the Partner ID, email, and password, with the server URL set at the default of “https://www.kaltura.com” —– and I get:

“You have successfully installed Media Pack”

“Unable to Connect Media Host Server!”
