urlopen error [Errno -3] Temporary failure in name resolution

[fbclol]

Hello,

I’m encountering a bug when trying to run the ImportWizardsAccountingData function in a Python macro within Collabora / LibreOffice.
The process fails with a URLError: Temporary failure in name resolution.

ScriptProtocolHandler::dispatch: caught com.sun.star.uno.RuntimeException: 
Error during invoking function ImportWizardsAccountingData 
in module file:///lo/share/Scripts/python/data-dream/DataDreamMacro.py 
(<class 'urllib.error.URLError'>: <urlopen error [Errno -3] Temporary failure in name resolution>)

Steps to Reproduce
1. Run the ImportWizardsAccountingData macro in Collabora / LibreOffice.
2. Provide a URL to fetch a CSV file.
3. Observe the error during the data import step.

⸻

Expected Behavior

The macro should download the CSV file and continue the import process without failing.

⸻

Actual Behavior

The macro crashes with Temporary failure in name resolution, meaning it cannot resolve the domain name when trying to fetch the CSV file.

Environment
• Collabora version: collabora/code:latest
• Python version: 3.10.18 (embedded in LibreOffice)
• LibreOffice environment: /lo/share/Scripts/python/
