Failed to construct 'WebSocket'Error

Hi,
I am currently trying to make a Rust server. I have setup the rust server perfectly on a rented machine. Now when I try to connect to the Web RCON, I seem to receive errrors it does not want to connect. 

I have put in the correct port and correct IP/password and nothing is working. I feel like I am missing something or something has to be installed. Here is the error I am receiving when trying to connect to the RCON.

Error: Failed to construct 'WebSocket': The URL contains a fragment identifier (''). Fragment identifiers are not allowed in WebSocket URLs.​
 

Still looking for help, if possible. 

I am brand new here so i have no idea what im doing really. But reads like you have an unwanted space somewhere in there.... but then again I have no idea what I'm doing either. I use the RustAdmin program for RCON connection
