This error means Cryptohopper tried to cancel an order but can't find it in your exchange's open orders anymore. The order still shows in Cryptohopper, but your exchange no longer recognizes it as active.
What causes this error
The bot was off for a while — If the trading bot was turned off with an open order still running, the order ID may no longer be retrievable from your crypto exchange when the bot is turned back on.
A temporary exchange disconnection — There may have been a brief disconnection via your API Keys or Fast Connect. This usually resolves itself automatically. If you see a warning on your Dashboard or Advanced Dashboard, you'll need to reconnect. Check our tutorials for all crypto exchanges.
API rate limit reached — Your exchange temporarily blocked API calls due to high activity. This is uncommon. If you're on Kraken, we recommend using 2 API Keys to increase your rate limit.
How to remove the stuck order
Go to the Orders tab in your Cryptohopper dashboard.
Find the stuck order.
Click Remove instead of Cancel. This removes the order from Cryptohopper without making any changes on your exchange.
After clicking Remove, the order disappears from your Orders tab and your bot can continue trading normally.
