TCA should stop Tor from trying to connect when we reach the error screen
This issue was inspired by: !435 (comment 173154)
Basically, now that TCA
SAVECONF:s all the time, if we fall back to default bridges but fail, then we have a
torrc which says we should use the default bridge, so if we restart TCA (e.g. after changing network to one where Tor is not blocked) it will immediately connect to the default bridge. This feels wrong.
So, perhaps TCA should try to reset the configuration after failures? I.e. drop all bridges, proxies and set
DisableNetwork = 1 again and
