How to Troubleshoot MT4 Login Issues
When login to an MT4 account is successful, data traffic numbers will be displayed. If an error message such as “Invalid account”, “No connection”, “Invalid account (in English)”, “Unauthorized account”, or “Authentication failed” appears at the bottom right of the screen, the login has failed.
If you are unable to log in, please try the following steps, which may resolve the issue:
1. Check your login credentials
2. Verify account validity
3. Confirm MT4 version
4. Check network environment
1. Confirm Your Login Credentials (Login ID, Password, Server Name)
The most common cause of login failure is incorrect login information.
For real accounts, please check the login details sent via email when the account was opened (Subject: [Important] Titan FX: MT4 Account Login Information).
For demo accounts, please recheck the login information displayed when the demo account was created.

We recommend using copy & paste to avoid typing mistakes.

・Number “0”, uppercase “O”, lowercase “o”
・Number “2”, uppercase “Z”, lowercase “z”
・Number “6”, lowercase “b”
Resetting Your Password (For Real Accounts)

④ Enter your desired password in both “New Password” and “Confirm New Password” fields, then click “Change”.

Confirming the Server
Titan FX currently has seven server types as listed below.
The server to select at login depends on the first digit(s) of your Login ID. Please make sure the server you selected is correct.
| Login ID Prefix | Server to Select |
|---|---|
| Login ID starting with 6 | TitanFX-01 |
| Login ID starting with 7 | TitanFX-02 |
| Login ID starting with 80 | TitanFX-03 |
| Login ID starting with 81 | TitanFX-04 |
| Login ID starting with 82 | TitanFX-05 |
| Login ID starting with 83 | TitanFX-06 |
| Login ID starting with 2 (demo account) | TitanFX-Demo01 |
If the above server names do not appear in the dropdown list during login, please try the following steps:
① From the top-left of the MT4 screen, click “File” > “Open an Account”.
② Click “Add new broker”, then type “titan” in the input field that appears, and click the “Scan” button.
Once the scan is complete and you have confirmed that the server you are using is listed, click “Cancel”.

③ After completing the above, you will be able to select other servers on the login screen.
2. Verify Account Validity
Check if Your Account Has Been Deactivated
Titan FX live accounts that have not been logged into for 90 days and have no positions, pending orders, or balance will be automatically deactivated.
Deactivated accounts will not be displayed in the trading account list on the dashboard of the Client Cabinet.
Deactivated accounts cannot be reactivated. Please create a new account by clicking the “Open Additional Account” button within the Client Cabinet.
Free demo accounts expire 30 days from the date of creation.
Expired demo accounts cannot be reactivated. Please open a new demo account on MT4.
Confirm the Account Is for MT4
Only MT4 accounts can log in to MT4. Please note that MT5 accounts cannot be used.
3. Confirm the MT4 Version
If you attempt to log in using MT4 or MT5 provided by another company, you may not be able to log in. Please always log in using the MT4 or MT5 platform downloaded from Titan FX.
4. Check Your Network Environment
If there are issues with your network environment, you will not be able to log in to MT4.
Network issues may be due to problems with your internet connection or system issues on Titan FX’s end.
Please check if internet communication (such as browsing websites) is working properly. If there appears to be no issue, please contact our support team.
We will provide information on the latest system status.
