Hello,

My coworkers and I are facing an issue when we try to execute the StreamingPrices function on a Python local environment.

Here is a typical example of what I am trying to run:




import eikon as ek

import pandas as pd



ek.set_app_key('my_api_key')



def get_eikon_data(contract, fields):



                streaming_prices = ek.StreamingPrices(

                    instruments=[contract],

                    fields=fields)

                streaming_prices.open()

                df = streaming_prices.get_snapshot().rename(columns={"Instrument": "Contract",

                                                                      "CF_TIME": "Timestamp",

                                                                      "ACVOL_1": "Volume"})

        return df

get_eikon_data('CLc1', ["ASK", "BID", "ACVOL_1", "CF_TIME"])

Now, here is the output we get: “Receive status message for unknown subscription id 2”

When running the logs, we get more details as followed:

The only thing I replaced is my API key. Everything else including john doe is from the logs.

Can you please check that out?

Many thanks.

    I can run the code properly.

    I could be network or firewall issues. The error indicates that it is unable to connect to the platform.

    2023-07-17 15:51:55,789 P[22328] [WebSocket 0 23228] Receive message for login 2: {'ID': 2, 'State': {'Code': 'ConnectionError', 'Data': 'Suspect', 'Stream': 'Closed', 'Text': 'Cannot establish connection to the platform'}, 'Type': 'Status'}

    Please contact the Eikon support team directly to verify what the problem is.
