Passenger keeps looking for wrong ruby version

I upgrade my ruby version to 2.6.5. I deployed it to my server using capistrano.

But my nginx logs say this:

App 9470 output: /bin/sh: 1: exec: /home/deploy/.rvm/gems/ruby-2.3.1/wrappers/ruby: not found
[ E 2022-01-27 12:34:23.7336 9450/Tc age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /home/deploy/taddar/current: The application process exited prematurely.
  Error ID: d1f83ca0
  Error details saved to: /tmp/passenger-error-0KwZUf.html

[ E 2022-01-27 12:34:23.7393 9450/T9 age/Cor/Con/CheckoutSession.cpp:276 ]: [Client 1-1] Cannot checkout session because a spawning error occurred. The identifier of the error is d1f83ca0. Please see earlier logs for details about the error.

When I run ruby -v I get 2.6.5, yet above you can see its looking for 2.3.1:

ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]

Any ideas on how to fix this?

In my deploy.rb I set the ruby version.

set :rvm_ruby_version, '2.6.5'

My nginx.config looks like:

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {
        passenger_ruby /usr/bin/ruby2.6.5;

        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include      /etc/nginx/mime.types;

Bingo got it working. Thanks to @razvans and @engineersmnky for pointing me in the right direction.

Yes I had references to passenger_ruby but it was in the wrong place. I had to go to /etc/nginx/sites-available and add passenger_ruby /path/to/ruby

To find out what the /path/to/ruby is use passenger-config about ruby-command and use the value at Command.

passenger-config about ruby-command
passenger-config was invoked through the following Ruby interpreter:
  Command: /home/deploy/.rvm/gems/ruby-2.6.5/wrappers/ruby

So mine was

server {
 ....
 passenger_ruby /home/deploy/.rvm/gems/ruby-2.6.5/wrappers/ruby

You might want to know any other references you have to ruby so they don't conflict with each other. A useful command is: grep -rnw 'path' -e 'passenger_ruby'

This doc helped me a lot https://www.phusionpassenger.com/library/deploy/nginx/deploy/ruby/#determine_ruby_command
