This message is documented [here](https://alpaca.markets/docs/api-references/market-data-api/stock-pricing-data/realtime/#control-messages). Most probably you have another connection with the same API key/secret opened. Only one active real-time connection is allowed now. The server has 90 seconds timeout for ‘partially dead’ connections so if you try to reconnect right after network-related disconnection (without proper web socket shutdown) using another socket you will receive this message too.

@chatofking Proper network resource closing depends on your programming language/library. In most cases, socket-related objects provide a method/function for closing the underlying connection. It can have names like `close`, `disconnect`, or something like this. Ideally, it should send a low-level WS protocol message to the server that indicates the end of the communication session and close the network socket after receiving a confirmation response from the server side.
