Trading Robot Backtesting Problem

I have created a trading robot but when I backtest it, it run well but without placing trades. On the journal report I see the message that says that cloud servers switched off and sometime the report shows that the maximum spread is exceeded, sometimes it says the volume is exceeded. I don't know how to come out of this. Is there any one who can help me to conquer this challenge? Thanks in advance.
