Designer error_Raspberry Pi OPC UA Server

I have an OPC UA Server within a Raspberry Pi. I have installed Ignition in Windows, but when I’m making my project in the designer, I can’t add any variable from the OPC UA Server in Perspective Home page. However I can add them to a Vision Window.
Apart from this , I can’t login in Vision Client Launcher. It says:
Login failed, please retry again.
I used the same username and password of Ignition edge.
