Comment (by yawning):

 Replying to [comment:3 arma]:
 > Your bridge may have bootstrapped to 100%, but that doesn't mean it
 could learn its address. The lines you quoted indicated that your bridge
 returned 404 when asked for its bridge descriptor. That is, it hasn't
 generated its descriptor yet. Perhaps if you set its address explicitly?
 What are the torrc lines for bridge and client?

 This is indeed possible, I do not have `Address` set in the bridge side
 torrc (Would specifying the loopback address break anything here?).

 Bridge:
 {{{
 SocksPort 0
 ORPort 9001
 ExtORPort 6669
 DataDirectory /tmp/tor-bridge/
 BridgeRelay 1
 PublishServerDescriptor 0
 ServerTransportListenAddr obfs4 127.0.0.1:52810
 #ServerTransportPlugin <Unrelated obfs4 stuff>
 #ServerTransportOptions <Unrelated obfs4 stuff>
 }}}

 Client:
 {{{
 SocksPort 9150
 DataDirectory /tmp/tor-client-obfs4
 UseBridges 1
 Bridge obfs4 127.0.0.1:52810 <Unrelated obfs4 stuff>
 ClientTransportPlugin <Unrelated obfs4 stuff>
 }}}

 I assume a configuration like this isn't something that's seen in the wild
 (probably only PT developers do this sort of thing?).  FWIW I haven't seen
 the client actually retry to fetch the bridge descriptor when I've
 triggered this in the past, and I've waited > 60 sec because I thought it
 might be the other bugs.
