Attention: during the night our server provider had to change the IP address of the server for technical reasons and without notice. Your orders will not work until you add the new IP address (22.214.171.124) to your API restrictions. To add the new IP, go to your Binance account and click on Manage API. Find the APIs used for SmartBinance and click on the "Change restrictions" button on the right, under the item "Limit access to trusted IP only" add the new IP address 126.96.36.199. During the next few days there may be other changes, but in this case you will be notified in time.
