Make sure you click BOTH auto trading options. The first is on the MT menu bar, the other is in the EA itself, on the "Common" tab ("Allow live trading")
Check your journal if it says successful and migrated. frowning is ok :) because the server allready migrated your EA. if you tuen it again to smile your platform in your pc and the Vps will trade simultaneously.
As I remember (it was written in some article) - autotrading is always ON in MQL5 VPS so EA should work anyway.
My MT5 broker uses OTP, when I use the Virtual Hosting from the MT5 platform itself, I keep getting an authorization on (my ip) failed (Invalid one-time password).
Write to service desk about it
