When encountering a "Common error" on the MetaTrader 4 trading terminal, it indicates a connectivity problem between the terminal and account servers, which may be unusually slow or completely disconnected.
While this error often resolves on its own with time, if the problem persists, consider the following troubleshooting steps:
- Close any charts that seem unresponsive or display "Waiting for update" for an extended period. b. Shut down and restart the entire trading terminal. c. Check your router's connection; turn it off and wait for 5 minutes before switching it back on to reset the connection. d. Temporarily disable your antivirus software to check if this resolves the common error. e. If possible, attempt to log in to your trading account from another computer to see if the issue persists; if it does, the problem may be related to the connection. f. Ensure that your trading server is correctly set for your trading account. g. Click on the connection bar at the bottom-right of the trading terminal and select "Rescan servers" to refresh the connection. h. Reinstall the trading terminal and attempt to log in again.
