Followed the deploy instructions; nginx throwing a 500 for rails app

Matt Bjornson asked in Servers

I'm not sure what happened, but I had a production environment/config working with nginx/passenger deployed on Digital Ocean. I am not seeing errors in log files, but nginx is throwing a 500 when I try to access the rails app.

sudo passenger-status

lastly /etc/nginx/conf.d/mod-http-passenger.conf

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
#passenger_root /home/deploy/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/passenger-6.0.4;
passenger_ruby /home/deploy/.rbenv/versions/2.7.0/bin/ruby;

What am I doing wrong? Any help would greatly be appreciated.
