What is 'requests.exceptions.HTTPError: 451 Client Error'??? (binance)

[zacra]

Hello.
I am operating a class that allows automatic sales through Python by communicating with CCXT through AWS server.

---

Traceback (most recent call last):
  File "/home/ec2-user/.local/lib/python3.7/site-packages/ccxt/base/exchange.py", line 613, in fetch
    response.raise_for_status()
  File "/home/ec2-user/.local/lib/python3.7/site-packages/requests/models.py", line 953, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 451 Client Error:  for url: https://fapi.binance.com/fapi/v1/exchangeInfo

However, some students suddenly encounter the above error and cannot call the API.

Was it blocked due to excessive API calls? Or is there another problem?
Please give me feedback on when such a message comes.

I also have the same problem when running auto trade in Binance Futures. The error appeared in the Google Cloud Functions. However, the ccxt seems to run well when I test it in my local debug environment(my notebook).

I guess it must be something wrong with BinanceAPI or they are changing policies toward API management.

I also got same problem nowadays like below.

HTTPError: 451 Client Error:  for url: https://fapi.binance.com/fapi/v1/exchangeInfo
ExchangeError: binance GET https://fapi.binance.com/fapi/v1/exchangeInfo

I'm testing on Colab and running on GCP linux server.
I already tried to check and upgrade version of ccxt and pyopenssl.

Keep me this post to get information to solve this problem.

Try running the code in an environment other than the US.
It looks like Binance has blocked the US API.

It makes sense they don't want to allow US customers, but to block their public api is a bit far. If anyone has a solution for client side workarounds other than connecting a device to a vpn/proxy, that'd be greatly appreciated. This is really screwing my project over.

It's quite an interesting behavior - we see similar behavior in CI (github actions runs on US Azure servers), however limited by time - seemingly to US "out of business" hours.

CI with active calls is passing fine during the european afternoon / evening - but is failing overnight / mornings.
I doubt regulations will change depending on the hour of the day - so this is pretty strange behavior.

如果是使用GCP Functions，可以透過以下方式解決，我已經可以使用了。
