Just wanted to add that I am also having this problem with TOR tab.
I am running:
Brave Version 1.73.105 Chromium: 131.0.6778.265 (Official Build) (64-bit)
On Windows 11 Education Build 26100.ge_release
On my home network with no restrictions.
and Tor browser can connect without any issue and without any bridge.
Just to reinforce this thread.
is there a way to access debug messages related to brave tor private browsing? like turn on debug messages and see where in the process it stops or errors out?
