Permission denied on socket with 5.0.8

[JasonBarnabe]

Upon upgrading my Rails site from Passenger 4.0.53 to 5.0.8, I'm greeted with a 502 error. Error log says:

2015/05/24 02:36:43 [crit] 20408#0: *179 connect() to unix:/tmp/passenger.FD57G8h/agents.s/server failed (13: Permission denied) while connecting to upstream, client: 1.2.3.4, server: userstyles.org, request: "GET / HTTP/1.1", upstream: "passenger:unix:/tmp/passenger.FD57G8h/agents.s/server:", host: "userstyles.org"

I have the following settings which may be relevant.

    passenger_user_switching off;
    passenger_default_user www;
    passenger_default_group www;

www is the user that started nginx (with sudo). www does not own all the files of the Rails app, but can r and x them.

Downgrading to 4.0.53, reinstalling the nginx module, and restarting brings things back to life.
