I have a very simple app with only a header test to be rendered on a home page that should be accessible at my server public IP, something like this:
http://54.88.181.57:3000
In development the app is working:
http://localhost:3000/
rendering the very simple message:
Tasks home page
In production Puma is available here:
$ ps -ef | grep puma
deploy 5653 1 0 16:23 ? 00:00:01 puma 3.6.0 (unix:///home/deploy/tasks/shared/tmp/sockets/puma.sock) [20160924162316]
The instance is a AWS EC2 Ubuntu 14.04 There are no issues with the DB which is a AWS RDS Postgresql database (accordingly with the production.log) and I can access it anytime using:
$ psql --host tasks.cbb3snhbk4wo.us-east-1.rds.amazonaws.com --port 5432 --username tasks --dbname tasks
Password for user tasks:

Don't know what is not right here and why I cannot access my app in production using the serve public IP and port 3000?
First, verify that Puma is indeed listening on port 3000 by running this command on the server:
netstat -an | grep 3000
You should see something like this:
tcp 0 0 0.0.0.0:3000 0.0.0.0:* LISTEN
If Puma is listening on port 3000, then perhaps a firewall or other security policy is blocking access.
If Puma is not listening on port 3000, then I suspect the config/puma.rb file that you pasted in your question is not actually being loaded. As evidence, I see in the logs that Puma is binding to unix:///home/deploy/tasks/shared/tmp/sockets/puma.sock, but in the puma.rb you've specified shared/sockets/puma.sock (without the tmp).
You haven't explained how exactly you started Puma, but whatever method you are using, make sure Puma is being sent the -C flag with the path to the puma.rb that you would like it to use.
If you are using the capistrano3-puma gem, then refer also to this related answer: Capistrano doesn't create puma.pid file
