 8/26/19, 20:54:06.827 [NOTICE] I learned some more directory information,
 but not enough to build a circuit: We have no usable consensus.

 authority key certs
 8/26/19, 20:54:08.289 [WARN] Your configuration excludes 100% of all
 possible guards. That's likely to make you stand out from the rest of the
 world.

 8/26/19, 20:54:08.289 [NOTICE] The current consensus has no exit nodes.
 Tor can only build internal paths, such as paths to onion services.

 8/26/19, 20:54:08.290 [NOTICE] I learned some more directory information,
 but not enough to build a circuit: We need more microdescriptors: we have
 0/0, and can only build 0% of likely paths. (We have 0% of guards bw, 0%
 of midpoint bw, and 0% of end bw (no exits in consensus, using mid) = 0%
 of path bw.)

 Loading relay descriptors
 8/26/19, 20:54:09.210 [NOTICE] The current consensus contains exit nodes.
 Tor can build exit and internal paths.
