The “Authorisation Failed” message on MetaTrader 4 (MT4) or MetaTrader 5 (MT5) may indicate incorrect login details, an incorrect server selection, server downtime, or a poor internet connection.
Common Issues
You may encounter this error for the following reasons:
- Incorrect login details: The trading account number or password entered may be incorrect.
- Incorrect server selection: You may have selected a server that does not correspond to your trading account.
- Server downtime: The trading server may be temporarily unavailable.
- Connection issues: A poor or unstable internet connection may prevent you from logging in successfully.
What Should I Do?
If you encounter the “Authorisation Failed” message, try the following steps:
- Check your login details. Make sure you are entering the correct trading account number and trading account password, rather than your Client Portal login credentials.
- Verify your server. Check the server assigned to your trading account on the Accounts page of your Client Portal and ensure you select the correct server in MT4 or MT5.
- Reset your trading account password. If you are unsure of your password, reset it through your Client Portal and try logging in again with the new password.
- Check your internet connection. Ensure your device has a stable internet connection before attempting to log in again.
