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

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.

Not sure exactly what the issue is here but StackOverflow (https://stackoverflow.com/a/54389947/79802) suggests reinstalling a few libraries:

pip uninstall cryptography
pip uninstall pyasn1
pip install pyopenssl
pip install cryptography
pip install pyasn1
