I'm new in stackoverflow and i have a issue with pip install. I didn't have it before. Last time when i have installed library was around month ago and everything was ok. Today when i tried to install new library i received error message:

ERROR: Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Max retries exceeded with url: /packages/6b/d9/bc4475685ae3005986d38c6e54f15a5afe8732f2fe98453b0c7f819e8b07/clock-0.1.tar.gz (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)')))

I'm using Python 3.8 32 bit on windows 10. Pip version is 20.0.2. Everything else is working but i'm not able to install new libraries which is a big issue.

  • Additionally this issue is not only on my PC, but on 2 more which are used as servers and basically no change has been made on any of the 3 PCs from my side.Those are corporate PCs and problem is presented with or without VPN connected. – stanislav Apr 08 '20 at 20:22

  • Thanks for the response, but i already try the solution with pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org --user and it is not working. I'm still receiving same error. – stanislav Apr 08 '20 at 20:38
  • Just for information - the issue was caused by internal umbrella/security systems which has blocked the traffic - when VPN is disconnected and connection is via proxy server it works, but the guys has unblocked the traffic. – stanislav Apr 09 '20 at 07:23
