"Cannot connect to server" Bot Xcode
Ok I figured it out, sort of. It has to do with the SSL certificate on the server. I ended up purchasing an SSL from GoDaddy because I could never get a self signed to work. I would recommend using some of the other methods, like storing your plist in DropBox if you don't want to pay for an SSL and can't get the self signed to work. 

This was after reaching out to apple and reading a post in the developer forums. Apple hopefully will fix this in the future.
