Problem installing Rasa X--Certificate verification failure

Trying to install Rasa X in a Windows Anaconda2 environment

(py36) C:\WINDOWS\system32>pip install rasa-x --trusted-host -i
Looking in indexes:
Collecting rasa-x
  Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:847)'),)': /rasa-packages/14b7/rasa-x/rasa-x-0.19.0.tar.gz?

@lgrinberg seems like maybe your machine doesn’t trust the SSL certificate. Can you see if you can download it directly from

After a while, I came back to this, downloading from didn’t really work, but I tried bypassing the certificate check for and that did work! pip install rasa-x --extra-index-url --trusted-host --trusted-host --trusted-host --trusted-host

Now Rasa X is installed
