A question about Orbot

When I run Orbot, after 25% it suddenly goes to 100% but it doesn’t work:

updating settings in Tor service
Updating torrc custom configuration…
Orbot is starting…
Connected to tor control port
Added control port event handler
NOTICE: Bootstrapped 10% (conn_done): Connected to a relay
NOTICE: Bootstrapped 14% (handshake): Handshaking with a relay
NOTICE: Bootstrapped 15% (handshake_done): Handshake with a relay done
NOTICE: Bootstrapped 20% (onehop_create): Establishing an encrypted directory connection
NOTICE: Bootstrapped 25% (requesting_status): Asking for networkstatus consensus

Why? Does something cut off the connection in the middle?

Thank you.
