If you got an edge to work on another machine, you can get it to work on the same machine. There is no problem in configuring origin and edge applications on the same machine, I have done it many times.
Why would you configure the origin application as the redirect application? They are totally separate applications. Sounds like you are improvising as you go instead of following the guides precisely, and/or you are skimming the instructions, which you just cannot do.
I suggest you start over, follow the provided instructions more carefully.
