Thank you for the test! I think that proves, that the issue is not in a (not) running proxy service. Also, did the same steps (after installing fedora-33 template which i didn’t originally had) - and it didn’t work. AppVM was based on ws-15, then I tried to connect with another fedora-33 VM (so f-33 to f-33) - and it worked. Then I ran some more tests and came to conclusions:
- Most OS can share to and receive internet from other qubes.
- Whonix Workstation 15 can’t. It can receive internet only from Whonix Gateway.
- Whonix Gateway needs to restart tor after switching network qube.
So, I guess this trouble is kind of solved (except I count ws-15 requirement for gw-15 as a flaw, but devs sure got strong reasons on that).
P.S. Weird how forum dedicated to privacy-centered OS requires JS for basic functioning (like log in or write a reply). But yes, all nojs-alternatives have worse UI.
