What Tor version are you using?

One of the changes in Tor is:
    - Hidden services no longer publish version 0 descriptors, and clients
      do not request or use version 0 descriptors. However, the old hidden
      service authorities still accept and serve version 0 descriptors
      when contacted by older hidden services/clients.

So if you're using Tor, the fix is to add the "hs" flag to
your dirserver lines.

The man page says:
       DirServer [nickname] [flags] address:port fingerprint

For some example lines, see add_default_trusted_dir_authorities()
in src/or/config.c, e.g.

If you're using Tor 0.2.2.x or later, though, the hidden service directory
servers are no longer centralized. We use a distributed hash table design
to spread the hidden service descriptors around all relays that have
the HSDir flag. The HSDir flag is only given to relays that have been up
for at least MinUptimeHidServDirectoryV2 seconds, which by default is 24
hours. My guess is that setting that config value to 0 on the directory
authorities should help in your case.

Were you using the TestingTorNetwork config option? If so, I think Tor
ought to set MinUptimeHidServDirectoryV2 to 0 for you automatically. But
it doesn't do that yet. I just opened a bug report to resolve it:
