There are various reasons why you might see 'Cannot cancel order because order is not listed in open orders anymore' in your trading bot output:
The trading bot has been turned off for a while, leaving an order open that was placed through Cryptohopper. If the trading bot is turned back on after a certain period, it may happen that the order ID can no longer be retrieved via your crypto exchange.
There has been a temporary disconnection from your crypto exchange via the API Keys or Fast Connect. This issue usually resolves itself automatically unless you see a message at the top of your Dashboard or Advanced Dashboard indicating there is a problem with your API Keys or Fast Connect. If this is the case, you will need to reconnect to your crypto exchange. Check our tutorials for all crypto exchanges on how to do this.
You have reached the rate limit for the number of API calls. This is uncommon but can happen during extreme activity on a crypto exchange. When using Kraken, we always recommend using 2 API Keys to ensure a higher API rate limit.
In all cases, we recommend manually removing the orders via "Info > Action > Remove" as shown in the screenshot below:
