Hi,  
I have followed the the documentation here: [Real-time data - Documentation | Alpaca](https://alpaca.markets/docs/api-documentation/api-v2/market-data/alpaca-data-api-v2/real-time/), and authenticate using the client key and secret created here [Open an Alpaca Securities Brokerage Account](https://app.alpaca.markets/brokerage/apps/manage). However I received these series of events:

```auto
[{"T":"success","msg":"connected"}]
[{"T":"error","code":402,"msg":"auth failed"}]
[{"T":"error","code":401,"msg":"not authenticated"}]
[{"T":"error","code":404,"msg":"auth timeout"}]

```

May I know what I did wrong?

Thanks,  
Kien

I am dealing with the same problem. I can connect just fine using a websocket client from chrome but using Golang client I cant. Have you found resolution with this? Seems no one responded.
