Hi, I have a python script which connects to TREP server through websocket api for getting real-time quotes. It works when I use the host name but not for IP address - the script need to run in an environment which is not aware of the machine name - any suggestions, thanks

WebSocket can only connect server with machine name but not with actual IP address

@lzhuang1, In addition to trying the "provided API samples", can you try to check if the IP address is listening on the websocket port: 15000.
Try:
>>telnet ip.ip.ip.ip 15000
Where ip is the IP address of ADS providing websocket connection.

@lzhuang1
Is there any error from your python script? and Is this possible to share your test app?
I usually use an IP Address to test the WebSocket on my ADS and not found any issue.
Can you also try WebSocketsAPI_TryitNow_Doc example from https://developers.refinitiv.com/elektron/websocket-api/downloads connecting to the server using the same IP Address and port?
You may also try a python example from WebSocket API Sample Applications to test the server. Then you can compare the result with your python script.
There is no errors when I use machine name to connect, The code is paste below:
ws_address = "ws://{}:{}/WebSocket".format("hostname", 15000)
print("Connecting to WebSocket " + ws_address + " ...")
web_socket_app = websocket.WebSocketApp(ws_address, header=['User-Agent: Python'], on_message=on_message, on_error=on_error, on_close=on_close, subprotocols=['tr_json2'])
web_socket_app.on_open = on_open
wst = threading.Thread(target=web_socket_app.run_forever)
wst.start()
When I change "hostname" to the actual IP of the same host, it complains on:
[WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
Please advise, thanks!
