@smellman Got a download error which appears in another way comparing to before.

エラー: Failed to download GTFS data from the URL: https://www.takubus.com/app/download/10941479479/GTFS_regular_line.zip?t=1606785205

Don't work as above comment

I run test in QGIS's Python console on Windows 11.

>>> import requests
>>> response = requests.get("https://www.takubus.com/app/download/10941479479/GTFS_regular_line.zip?t=1606785205")
>>> response.status_code
429

429 is Too Many Requests.
I think it is server reason, but, I can run above code without error in macOS and Windows 11 Powershell.
I will check requests modules with windows bug.
