Boostrap error

Hallo. After an hour of working suddenly an error table appeared in Gateway: Tor bootstrap error, whonixcheck exit after 0 sec. Is host connection working? Do you live in censored area? . . . (I forgot to printscreen it)
I didnt notice whonixcheck was running before in Gateway.

So I started whonixcheck and it showed no error, connected to tor. Also in workstation everything worked before, no failures.
Did all my traffic went thru tor safely?

This does not indicate leaks. Only temporary network failure.
