Server issues for 2d platformer

My 2d platformer is being weird, I set replicate for everything on, and I still can’t get my two characters to see each other, I run it on the 2 clients and use the same default unreal server that is 127.0.0.1 They are in the same server because when I print a string it does the Server:Hello on both of them, any suggestions on how to get my two characters to see each other?
