Wacky! @btlechowski Do you have full console output from that?

[riastradh-brave]

Also, can you share ${BRAVE}/tor/data/tor.log? (~/.config/brave/tor/data/tor.log on Linux, %appdata%\brave\tor\data\tor.log on Windows, substituting brave-development or brave-beta for brave if a nonstandard channel.)

Even after connecting back to network, still doesn't connect to Tor and opening a new Tor tab doesn't show the retry/disable popup . The only option is to restart browser to connect again to Tor
