1. “Invalid Account” error is usually experienced when:
1.1 Trying to login using incorrect credentials, please ensure that you are using the correct MT4 account, password, and server.
1.2 Using an old version of MT4 Terminal, an update of the terminal can solve this problem.
1.3 This error might be related to the status of the account. If the account is disabled, this error will be produced. If you are sure that you are entering the correct credentials and still receiving this error, please contact us at Supoprt.email@example.com
2. “No Connection” Error:
No Connection error is usually experienced when the client has failed to connect to the MT4 server. To solve this problem, please check your internet connection. Another cause of this issue is that your anti-virus/firewall is blocking the connection. Please allow connection to the MT4.
