Currently, Im trying to bootstrap Tor on Whonix.
The screen says as below.

Bootstraping Tor...
Bootstrap phase: Starting
0%

However, it's been 30minuites since this started.
Does Bootstraping Tor take such a long time as usual?
Or is this only in my case and it's happening because of some kind of trouble on my computer?

I would appreciate it if you solve this matter for me.
thanks.
