reference error:mystamp is not defined

Hello, a week ago I bought gunbot.
In the beginning everything was good. After a few days I could not call single pages error message code422.
I have generated a new API key and then ran nothing.
I could not connect to any side.
Now I have used the old API key again.
Now gunbot connects with the sides. But he can not recognize the balance or the price of the currency.
I can not continue trading.
What am I doing wrong?
The error is shown: cycle failed
