Xcode 9 Bot creation

I'm trying to set update a previous Xcode BOT. Can anyone help?


When I choose the repository for the BOT, I'm asked to sign in. The popup window shows Login (which I choose as "Personal SSH Keys", User Name and the SSH Key. When I chose "Personal SSH Keys" it asks me for a User Name. I don't know why but anything I enter here does not work. I get the error message: "Authentication failed becuase there authenticatio credentials were rejected" I've tried SSH keys with and without passphrases. I know the SSH keya work (as I use them with SourceTree


What is the User Name it is asking for (I have tried the server User Name and my local User Name)?


Thanks!
