Why do I receive ‘Invalid account’ or ‘No connection’ error?

If you see ‘Invalid Account’ or ‘No connection’ error when using MT4 platform, it may be caused by the following reasons:

1. ‘Invalid Account’ error means that the account number, password or the server was entered incorrectly.

2. If you see ‘Invalid Account’ error when logging in to the demo account, in addition to the reasons mentioned above, your demo account may have expired. In such case you need to open a new demo account.

3. ‘No connection’ error may be caused by poor internet connection or a problem with the server.

To solve the difficulty, you can try following the next steps:

1. Incorrect account credentials

• Make sure you enter your username and password correctly. Usernames usually contain numbers and letters, and passwords are case-sensitive.

2. Wrong server 

• Make sure you select the correct server. When logging in, it is necessary to select the corresponding broker's server.

3. Network connection issues

• Check your network connection to make sure your device can access the internet. Try reconnecting to the internet or restarting your router.

4. Broker server issues

• Sometimes, the problem may be on the broker’s end, such as server maintenance or outages. It is recommended to check the broker's official website or contact Customer Support.

5. Firewall or security software

• Some firewalls or security software may block MT4's connection. Check your firewall settings to make sure MT4 is allowed to access the network.

Workaround

• Re-enter account information：make sure your account and password are correct.

• Check the server：select the appropriate server in the login window.

• Check your network connection：make sure that the network connection is good.

• Update MT4：sometimes updating the software can help resolve connection issues.

• Contact the support：if the problem persists, it is best to contact the Customer Support for further assistance.
