CCXT proxy issue

CCXT Version

4.2.21

Description

Context: I'm living in China and you may know we have the great fire wall. I usually use V2rayN on my PC to search content using Google or login to the website which are forbidden in China.

Basically, I can call the BInance API using its official connector binance-connector-python. However, when I tried to use cctx to pull the data, it's not working from my end. After that, I've searched and read a lot docs on the Internet and none of them solve my problem. Can you help me with that? Thanks!

Code

from binance.spot import Spot

client = Spot()
print(client.klines("BTCUSDT","1h",limit=10))

import ccxt

binance_exchange = ccxt.binance()
ticker_data = binance_exchange.fetch_ticker('BTC/USDT')
print(ticker_data)

1) can you tell, do you access: https://api.binance.com/api/v3/exchangeInfo from browser directly? 2) do you have a chance to test out in other language (other than python, because I suspect it might be using OS's unproxied calls), so with nodejs you run i.e. this script: https://github.com/ccxt/ccxt/blob/master/examples/js/fetch-ohlcv.js

Thanks for your reply.

1. Yes, I tried and it's able to access the link and get the data from browser.
2. No, I haven't tried.

Never mind, I migrate all the codes to an AWS servre. Everything works there. Thank you!

你好，我也遇到了同样的问题，使用了vpn，错误提示是RequestTimeout: binance GET https://api.binance.com/sapi/v1/capital/config/getall?timestamp=1725611533376&recvWindow=10000&signature=9f8f60ae68f12e2ad08ca78d5862dd3838889f5a358a8d9270c63de29117a6f0 ，以前vpn还能获取数据，现在获取不了了，这个问题你后面解决了吗

[BangyuanX]

没有解决，我用freqtrade了

If you use proxies or VPN (like lantern) you might look in the answers: https://github.com/ccxt/ccxt/issues/9234
