Hello :wave:

Thank you for reporting. Would you be able to share which branch are you using?

• actually the issue occurred in from the chapter01 when running Streamer.start_streaming("xrpusdt")

• I tried to solve it by change elixir version from Elixir 1.13.2 (compiled with Erlang/OTP 24) to Elixir 1.10.0 (compiled with Erlang/OTP 22)

• when using elixir 1.13.2, it has a warning

 ==> binance
Compiling 17 files (.ex)

Generated binance app

• when using elixir 1.10.0, it has the same timeout issue, the following error info is in chapter06

Hello,

Thanks for more info - I wonder, maybe your network is somehow blocking the WebSocket port - could you please give it a try without specifying the port inside the Streamer.Binance module:

-  @stream_endpoint "wss://stream.binance.com:9443/ws/"
+  @stream_endpoint "wss://stream.binance.com/ws/"

I checked, and it works for me with and without specifying the port, so maybe it will help :thinking: :shrug:

[Cinderella-Man]

I just realised that you couldn't even fetch the exchange info from the Binance API (a RESTful API at 443[I guess]). Can you actually reach Binance?

Could you give it a try through your browser?

https://api.binance.com/api/v3/exchangeInfo or US based API: https://api.binance.us/api/v3/exchangeInfo

Does any of those work for you?

[sundevilyang]

I can reach the API through the browser.

Much thanks to you for helping me.

It still shows the error {:error, %WebSockex.ConnError{original: :timeout}} without specifying the port

I am using v2ray to visit binance.com, the v2ray server is located in Hongkong.

my v2ray server port is 443, I guess it may be the cause. let me figure it out and then let you know the result.
