The problem is that you will always fetch the username of the Server, not the Client - it looks like it works on your development machine because it runs on the same computer and IIS local host executes under your user ID. C# code always executes on the Server, never on the client - which can basically only run Javascript.
When you release to production, the code retrieves the username for the server running IIS, which is likely to be blank as it's not running as a "real" user.
You cannot retrieve the login username for a client in C#, and you can't get it in all browsers in javascript.
