Phusion Passenger is currently not serving any applications

Question

I got error like Phusion Passenger is currently not serving any applications. while trying to restart passenger with passenger-config restart-app comm

Answer 1

I am betting your passenger is running.
If you look at step 3, it hints at what I am talking about.

Nginx will take care of passenger for you if it's set up to do that. Can you try the command in that tutorial and look for passenger processes too ?

sudo /usr/sbin/passenger-memory-stats

Good luck!
