i am using crawlera from 2 months , it was woking fine but got this error :

"/home/vocso/.local/lib/python3.6/site-packages/urllib3/connection.py:362: SubjectAltNameWarning: Certificate for www.google.com has no `subjectAltName`, falling back to check for a `commonName` for now. This feature is being removed by major browsers and deprecated by RFC 2818. (See https://github.com/shazow/urllib3/issues/497 for details.)

here is my code

proxy_host = "proxy.crawlera.com"

proxy_port = "8010"

proxy_auth = "<key>:"

proxies = {"https": "https://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port),

"http": "http://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port)}

photon_requests_session = requests.sessions.Session()

photon_requests_session.verify = certifi.where()

r = requests.get(url,proxies=proxies,verify="crawlera-ca.crt")

soup = BeautifulSoup(r.text,'html5lib')

That's just a warning about an urllib3 feature support, not an error. The request still goes through the proxy and can get a response, so it can be safely ignored.

Can you please help me in the on this above question,

I am getting 'bad_proxy_auth' error while trying to test run the code. I am using requests version 2.19.0

url = "http://httpbin.org/ip"
proxy_host = "proxy.crawlera.com"
proxy_port = "8010"
proxy_auth = "<APIKEY>:" # Make sure to include ':' at the end
proxies = {"https": "https://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port),
      "http": "http://{}@{}:{}/".format(proxy_auth, proxy_host, proxy_port)}

r = requests.get(url, proxies=proxies,
                 verify=False)

Bad Authentication is a client side error, if the API Key being used is the correct one, then the only I can think of is the python requests version installed which might be causing problems.

Are you sure you're using the same script in both local and AWS?

Please add a more verbose response like in the sample: https://support.scrapinghub.com/solution/articles/22000203567-using-crawlera-with-python-requests (e.g. response headers)
