Hi I'm new to Nifi. I have been experimenting with it and trying implement Site to Site connections between different Nifi instances on a Windows box and a Linux box. I configure a remote procedure group and it can see the names of the input ports (somewhat confusingly named 9992 here) and can connect to them but when I try to transfer a file I get an UnknownHostException. Any help would be greatly appreciated.
