Binance signature error : “code”:-1022,“msg”:“Signature for this request is not valid.”

When trying to hit the route ‘’, I get the following error:
{“code”:-1022,“msg”:“Signature for this request is not valid.”}
signature =“utf-8”), query.encode(“utf-8”), hashlib.sha256).hexdigest()

headers[“X-MBX-APIKEY”] = self._access_key

response = await session.get(url, params=params, headers=headers, timeout=100, **kwargs)

print("======ceshi_nowTime=====",nowTime , response.status)
print("======ceshi_response.text======", response.text)

The client uses Alibaba cloud(alicoud+v6n)
1、when I tested SHA256 with the official API without any problem,
2、timestamp also no problem,Computer time is the time of GMT International time,When I url add recvWindows=5000 it’s 1022 the same mistake
3\so I never found out what the problem without( X-Cache’: 'Error from cloudfront),Does anyone have any suggestions ,thanks

Valid request url would be:

You can consult to check signature generation for different langs.

1、My connection was always successful before, but suddenly the connection failed
2、After I regenerate the API secret key, it is still not successful

=====print url is======

I just made sure there was no problem ,and Whether Ali cloud server has a problem or “Error from cloudfront”??

Do you have more information on the returned error message? It doesn’t seem to be a Binance error, but coming from “Cloudfront”.
What happens if you try to send the same request with ?

(Also, for safety, don’t show your signature here)
