How can I resolve an MT5 Android authorization failure caused by an incorrectly copied password?

If you receive an "Authorization Failed" or "No Connection" error when logging into MetaTrader 5 on Android — even though the same credentials work on MT5 Windows Desktop — the most common cause is an incomplete password entry. MT5 passwords may include special characters (such as a colon :) at the end, which can be missed or cut off when copying and pasting on a mobile device.

To resolve this, carefully copy and paste the full password, making sure all characters including any trailing symbols are included. Also ensure you are using the correct MT5 app (not MT4/MTQL) and the correct server name (e.g., MavenTrade-Server). Once the complete password is entered, the login should succeed. If it still doesn't go through - you can contact support.
