The '-1000 An unknown error occurred' error comes from Binance, not Cryptohopper, so we can't fix it. This error code means Binance is experiencing an unknown issue on their end. Their systems will automatically detect the problem, and their team will resolve it as soon as possible.
What to do
Your bot will automatically resume normal trading once Binance has resolved the issue. You don't need to make any changes in Cryptohopper.
If you want an update on the status of the issue, you can contact Binance directly.
