Packaging PySide6 with Nuitka - import QtNetwork causes issues - qt.network.ssl: No functional TLS backend was found

Nuitka version 0.6.19.4 Commercial: None Python: 3.9.7 (default, Sep 16 2021, 16:59:28) [MSC v.1916 64 bit (AMD64)] Flavor: Anaconda Python Executable: C:\tools\miniconda3\envs\smartblur_env\python.exe OS: Windows Arch: x86_64 WindowsRelease: 10

• How did you install Nuitka and Python pip install Nuitka in a conda env

• The specific PyPI names and versions conda.exe install pybind11 libsodium ninja libopencv nomkl numpy=1.21.4 pyopengl pywin32 openssl -y

  python -m pip freeze Nuitka==0.6.19.4 numpy @ file:///D:/bld/numpy_1636145505783/work pybind11 @ file:///D:/bld/pybind11-split_1641689025977/work pybind11-global @ file:///D:/bld/pybind11-split_1641689025977/work PyOpenGL==3.1.5 PySide6==6.2.2.1 pywin32==303 shiboken6==6.2.2.1

• Provide in your issue the Nuitka options used

nuitka --standalone --plugin-enable=pyside6 --plugin-enable=numpy --plugin-enable=anti-bloat --output-dir Packaging_video_test --static-libpython=no video_test.py

The problem is with packaging my app with Nuitka. It creates the executable but when I launch the executable I got those errors, and the part of the app related to QtNetwork is not working:

qt.network.ssl: No functional TLS backend was found qt.network.ssl: No functional TLS backend was found qt.network.ssl: No TLS backend is available qt.network.ssl: No functional TLS backend was found qt.network.ssl: QSslSocket::connectToHostEncrypted: TLS initialization failed

I didn’t have those errors before including QtNetwork. I suspect an issue with OpenSSL but I don’t know how to solve it. If I run my app from the terminal: python video_test.py, everything works fine. I have openssl=1.1.1l=h8ffe710_0

Thanks for your help!

Yes, minimal is great. I am pretty sure this about Anaconda, and figuring out their differences there will take some time.

Yes, seems to be a case of not using --include-qt-plugins with required values. Since this never got a reproducer, I don’t see any value in this issue anymore.
