 > What does tor say in its logs?

 The main repeated part:

 {{{
 Oct 28 05:43:00.000 [notice] Heartbeat: Tor's uptime is 2 days 17:59
 hours, with 7 circuits open. I've sent 15.08 GB and received 482.17 GB.
 Oct 28 05:43:00.000 [notice] Average packaged cell fullness: 43.617%. TLS
 write overhead: 4%
 Oct 28 05:50:28.000 [notice] Have tried resolving or connecting to address
 '[scrubbed]' at 3 different places. Giving up.
 Oct 28 05:57:49.000 [notice] No circuits are opened. Relaxed timeout for
 circuit 40835 (a General-purpose client 2-hop circuit in state doing
 handshakes with channel state open) to 10000ms. However, it appears the
 circuit has timed out anyway. 0 guards are live. [53 similar message(s)
 suppressed in last 3600 seconds]
 }}}

 I can't figure out reasons with that, but maybe you do.

 There are also some of the type:
 {{{
 Oct 26 23:33:59.000 [warn] Tried connecting to router at REDACTED, but
 identity key was not as expected: wanted REDACTED but got REDACTED.
 }}}
