It doesn't seem to connect to the Corel servers any more - just OneDrive and Flickr. Corel 2018 still connects to Corel but the icon in 2019 to use Connect opens the 2018 version, and the "connect" tools in 2019's WIndows/Dockers panel doesn't have the Corel server listed.
In CorelDraw 2019 go to "get more" and you now can download it all to your machine, fonts, clipart, images, templates, everything to your machine. Scroll through get more and it's all the ones listed without a $ale price. Much better.
Once you download you will see it in connect.
