HTTP connect with python to yubihsm-connector - Timeout

[Pymann]

So everything is running fine i can see status with curl and the connector claims to see the device:

But when i want to connect with python, I'm using the example Code: https://developers.yubico.com/YubiHSM2/Component_Reference/python-yubihsm/

I get http timeout, I have attached strace-log. st_log_sign.txt

It looks to me like the example code in that link is incorrect/outdated in regards to the URL. Compare it to the sample code here: https://developers.yubico.com/python-yubihsm/

Based on your trace, it looks like this is causing an extra /connector to be added in the request. Please try dropping the path from the URL and providing it as hsm = YubiHsm.connect('http://localhost:12345') instead.

So Curl answers to this URL: http://localhost:12345 404 page not found (server seems to answer) and i still face timeout with python.

So Exception shows now correct URL: Max retries exceeded with url: http://localhost:12345/connector/api

... still timeout. I also wonder about the port: port=3128

curl shows: curl http://localhost:12345/connector/api Method Not Allowed

[Pymann]

I tried to reduce the problem with following script:

from six.moves.urllib import parse
import requests

url="http://www.google.de/"
timeout = None

_url = parse.urljoin(url, '')
print(_url)
_timeout = timeout

_session = requests.Session()
msg="hi"

try:
    resp = _session.post(
        url=_url,
        data=msg,
        timeout=_timeout
    )
    resp.raise_for_status()
except Exception as e:
    raise Exception(e)

And still timeout occurs, so problems is about requests-module. Or settings of it or of OS.

I dont think problem is up to yubihsm

Theres left to say, that requests python lib is buggy concerning proxy-servers, issues are known.
