Hi All,

Following the instruction @ https://docs.qatrackplus.com/en/stable/install/win.html
Successfully run the SQL Server
Successfully run the QATrack31cherryPyService
But after I open localhost:8008 in the browser (chrome & edge), it shows the error "This page isn’t working right now". Then I see the following message in cherry_py_err

ImportError: DLL load failed while importing _openssl: The specified module could not be found.

pyopenssl: 21.0.0
cryptography: 3.4.8
python: 3.9.1
windows 10

Not sure which DLLs are missing and what's those DLL files?
Any help is appreciated.

Thank you.

Hi Huan,

This is not an error I've run into.   As a first step I would activate your virtualenv, ensure pip is up to date and try reinstalling pyopenssl and cryptography:

pip install --upgrade pip

pip uninstall pyopenssl cryptography

pip install pyopenssl cryptography

and ensure you can import openssl:

python -v -c "from OpenSSL import SSL"

then if that works, restart the cherry py service.
