• HTTP 418 return code is used when an IP has been auto-banned for continuing to send requests after receiving 429 codes.
• HTTP 5XX return codes are used for internal errors; the issue is on Binance's side. It is important to NOT treat this as a failure operation; the execution status is UNKNOWN and could have been a success.

Code
{
  "code": -1121,

}
