Following the horizon getting started guide

npm install -g horizon
hz init example_app
hz serve --dev

with RethinkDB 2.3.0 installed

leads to

... that error many times
Horizon failed to start after 30 seconds
Try running hz serve again with the --debug flag

Running with RethinkDB 2.3.2 leads to

Horizon ready for connections 🌄

rerunning that command with RethinkDB 2.3.2, the issue doesn't reappear.

If you're reporting a bug please include the following:

• Server version: RethinkDB 2.3.0 and 2.3.2
