I've done that a few times already without success, though I'll try it a little more. I guess I should note that the webpage inside the net7 client doesn't connect either, it shows up as connection cannot be established right away.
Edit: I tried it a few more times and it did indeed update. It even showed the webpage this time. I'll still report that it does have a connection error on the bottom, but other than that things look normal.
Edit #2: So now after I hit play, whether it doesn't show it has a connection error on the bottom or not, the Net7Proxy will give me the "Server failed to respond to login attempt" error. I've tried using the same method as before but with no luck thus far.
