Infuse can't connect to my NAS storage

I can’t connect Infuse 4 installed on an Apple TV 4 with my WD MyCloud EX2.
I can see the device on the list, to choose the connection, but when I click on the Save button it keeps turning around and doesn’t connect. What can I do?

Username, password, … Samba (SMB/CIFS) … Play

Thank you ClonyXXL but I already solved the issue just sharing the volume mounted on my iMac. I know it’s tricky, but it works.
