Python Eikon Data API 503 error

Hi, I'm having some trouble with using Eikon Data API, I've just followed https://developers.refinitiv.com/en/article-catalog/article/eikon-data-api-python-troubleshooting-refinitiv to find where is the problem, but still cannot resolve yet.

Basically, I want to try the following python command

import eikon as ek
ek.set_log_level(1)
ek.set_app_key("key")
print(ek.__version__)
data = ek.get_timeseries('AAPL.O',  # the RIC for Apple, Inc.
                         fields='*',  # all fields
                         start_date='2023-01-01',  # start date
                         end_date='2023-07-01')  # end date

But I'm having this log at the `ek.set_app_key("key")` line

[2023-08-03 10:41:22,642;s] - [INFO] - [log] - Send GET request to http://127.0.0.1:9000/api/status to detect API Proxy...

Funny thing is if I try the following code, it works

import requests

requests.get("http://127.0.0.1:9000/api/status")

with 200 response

Can you help me use Eikon DATA API?

my python eikon package version is 1.1.17 and running REFINITIV WORKSPACE version is DESKTOP 1.22.303 (or running REFINITIV EIKON version is Desktop 4.0.62(4.0.62015)

It may relate to the proxy (squid).

You may try to set the NO_PROXY environment variable, as mentioned in this discussion.

import os
os.environ['NO_PROXY'] = 'localhost'
os.environ['NO_PROXY'] = '127.0.0.1'

I'm working behind our company firewall and using company-wise proxy server also. Should we allow some connection to use it? If so, can I get some ip or any information we need to allow connection?

BTW, then how the following works?

import requests requests.get("http://127.0.0.1:9000/api/status")

I'm behind the company firewall and using company-wise proxy server together. Should my company allow some connection? If so, any ip or information which we should allow?

Thanks

Thanks! It's working with that modification!
