 Of course, Snowflake works and I have no idea why the guard must be
 failing. Moreover, it says that message right after the 85% in the
 bootstrap and 90%:

 {{{
 [notice] Bootstrapped 80%: Connecting to the Tor network
 [notice] Bootstrapped 85%: Finishing handshake with first hop
 [warn] Your Guard [scrubbed] is failing an extremely large amount of
 circuits. This could indicate a route manipulation attack, extreme network
 overload, or a bug. Success counts are 50/169. Use counts are 73/76. 162
 circuits completed, 1 were unusable, 112 collapsed, and 4 timed out. For
 reference, your timeout cutoff is 60 seconds.
 [notice] Tor has successfully opened a circuit. Looks like client
 functionality is working.
 [notice] Bootstrapped 100%: Done
 [warn] Your Guard [scrubbed] is failing a very large amount of circuits.
 Most likely this means the Tor network is overloaded, but it could also
 mean an attack against you or potentially the guard itself. Success counts
 are 52/171. Use counts are 73/76. 164 circuits completed, 1 were unusable,
 112 collapsed, and 4 timed out. For reference, your timeout cutoff is 60
 seconds.
