connection refused

[Long199for]

I'm running your example, and got time out on ssl or refused. And I found that even if I use:
import requests
h = {
"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36",
}
r = requests.get('https://api-testnet.bybit.com/spot/quote/v1/kline?symbol=ETHUSDT&interval=5m', headers=h)

I still got refused.

while if I use:
import urllib.request

req = urllib.request.Request(web, headers=headers_)
data = urllib.request.urlopen(req).read().decode("utf-8",'ignore')
print(data)

I could get the result.
We know that the kline is unauthorized url. So I wonder if requests library is treated as ROBOT ?
