The interfaces of MT4 and MT5 may differ slightly, but the login process is the same for both platforms. Here’s how you can add your broker server.
Open MT4/MT5 inside your VPS
Click File then Login to Trade Account
Input your broker Login, password of your account and choose the Server then click Login
Your account should now be visible under Navigator
That’s it, you have successfully added your broker server to your MT4/5 platform.
Tip: If you face issues, confirm the server details with your broker or restart your MT4/5 platform.
