TCA does not connect with default bridges when it should
There actually are two bugs here but i have only one screencast and one log so i will describe both here:
- Checked "Configure Tor automatically (easier)
- Checked the checkbox "Configure a Tor bridge"
- Clicked "Connect to Tor"
- Checked "Use a default bridge"
- Clicked "Connect to Tor"
TCA will tell you they are blocked but actually they aren't.
(That's bug number one)
Now "fool" TCA by clicking one of the options in the "Error connecting to Tor" window without changing anything and TCA will now allow you to try connecting again.
- Clicked "Connect to Tor"
TCA will now connect you to Tor without bridges which is clearly not what i wanted.
(That's bug number two)
After step 6 the behavior was different almost every time.
In the videos you will see that connecting without bridges succeeded this time.
But sometimes TCA will fail and will then try with default bridges again.
Sometimes that works. Sometimes it doesn't and you will be back at the "Error connecting to Tor" window.
(My network conditions are the same like on #18303 (closed)).
