Cannot connect to Marketplace
i would like to use Group into Collection Operator. So i need Operator Toolbox. For Operator Toolbox i need to extend Operator in Marketplace. If i click on Get more operators from Marketplace. I get this kind of error
So i did manually as already explained in this link
I downloaded Operator Toolbox .jar file (https://marketplace.rapidminer.com/UpdateServer/faces/download.xhtml?productId=rmx_operator_toolbox&platform=ANY&version=2.6.0) and moved to .Rapidminer > extension Folder. Then i reopened Rapidminer Studio. Still i get this kind of error.
if anyone know, how i can solve this problem or another way to install Operator Toolbox, could you please help me out?
