Do I need a OSX machine to package from UE4 and install it in iOS devices?

I was able to create an .IPA once, now every time I try it errors out and says "Remote compiling requires a server name. Please specify one in the Remote Server Name settings field. Not sure why this is coming up now, considering I was able to both launch to IPAD and package to .ipa. You think there is a setting I checked? I’m using Windows 10 and Unreal Engine 4.17.2
