Over the past few weeks I have been working on a multiplayer game that uses Unity’s Master server. At first, My Script worked great and I was able to connect to servers on other computers without a problem. However today I have been trying to use the script but whenever I create a server on one computer and refresh the available servers on another, the unity editor returns the error “Failed to connect to master server at 67.225.180.24:23466” and the server I created does not show up on the server list.
Here is the code I use to connect to the master server:

Any help would be appreciated.
