CERTIFICATE_VERIFY_FAILED

[ati666]

Why do I get CERTIFICATE_VERIFY_FAILED error?

requests.exceptions.SSLError: HTTPSConnectionPool(host='www.ryanair.com', port=443): Max retries exceeded with url: /hu/hu (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1123)')))

All my code was just the initalization:

'from ryanair import Ryanair

# You can set a currency at the API instance level, so could also be GBP etc. also.
# Note that this may not *always* be respected by the API, so always check the currency returned matches
# your expectation.
api = Ryanair("EUR")'

If you do something like

import requests

requests.get("https://example.com")

do you get a similar error?

If so, you're probably behind a proxy that's signing with its own cert. The library requests uses certs from certifi, rather than the system certs, so it won't necessarily see the proxy's own cert as valid, even if the system generally does.

You can override this behaviour of you want your traffic to trust this intermediate cert. In Windows you can override this by with something like the pip-system-certs package. On Linux, you can set an environment variable pointing either/both requests and urllib at the system ca certs.

Thanks! I Think my VPN was the root-cause of this issue as I now I don't get that error.

from datetime import datetime, timedelta
from ryanair import Ryanair

api = Ryanair(currency="EUR")  # Euro currency, so could also be GBP etc. also
tomorrow = datetime.today().date() + timedelta(days=1)

flights = api.get_cheapest_flights("DUB", "2023-09-22", "2023-09-23")

and for this I'm getting

  File "C:\Users\user\PycharmProjects\flypy\venv\lib\site-packages\backoff\_common.py", line 29, in _init_wait_gen
    initialized = wait_gen(**kwargs)
TypeError: 'staticmethod' object is not callable

do you have any idea whats wrong?

[cohaolain]

What version of python are you on? I don't seem to be getting this when running the sample you provided.
