Thank you for reaching out to us.

This issue may relate to the proxy settings on your machine. You can use the following code to verify what the problem is.

import httpx
import lseg.data._core.session.proxy_info as proxy_info
from httpx._utils import get_environment_proxies
from typing import Union, Tuple, Dict, List

orgClient =  httpx.Client
org_get_proxy_for_httpx = proxy_info.get_proxy_for_httpx

def newClient (proxy, **kwargs):
    print("### New httpx.client ###")
    print("Check Proxy:")
    print(proxy)
    print("Check kwargs:")
    print(kwargs)
    return orgClient(proxy = proxy, **kwargs)


def new_get_proxy_for_httpx(proxies: Union[str, Dict[str, str]]) -> Dict[str, str]:
    print("### new_get_proxy_for_httpx ###")
    print(proxies)
    print("### env proxy ###")
    print(get_environment_proxies())
    temp_proxy_value = org_get_proxy_for_httpx(proxies)
    print("### Return new_get_proxy_for_httpx ###")
    print(temp_proxy_value)
    return temp_proxy_value

httpx.Client = newClient
proxy_info.get_proxy_for_httpx = new_get_proxy_for_httpx

import lseg.data as ld


ld.open_session(config_name='./config.json')

Then, please share the console output.
