catalog is not shown (cannot download https://apps.0install.net/catalog.xml)

I just have installed the freshly 0install on Windows 10 Pro, and no apps are displayed in catalog.
Does the problem still occur? Perhaps it was only a temporary network issue.
If the problem still persists, could you post the contents of the file %TEMP%\ZeroInstall %USERNAME% Log.txt?
Will do that on Monday, form my virtual machine.

No, I copy-pasted the url in firefox, and it was opened correctly. I also tried a few reboots.
Do you have any kind of HTTP proxy settings configured in Firefox? Zero Install uses the OS-level proxy settings (i.e., the ones available under ms-settings:network-proxy).

No. I have no proxy in system nor in FF
