Facing authentication issues while deploying Rails App on AWS EC2 using capistrano

I first deployed using git clone in /var/www/AppName directory and was able to successfully deploy it. I then tried using capistrano and link it with my git. I am following this Link to deploy app using capistrano. I am facing authentication issues.

My deploy.rb file is

set :application, 'blog'set :repo_url, 'git@github.com:abc@def.com/blog.git'set :branch, 'master'set :linked_dirs, fetch(:linked_dirs, []).push('log', 'tmp/pids', 'tmp/cache', 'tmp/sockets', 'vendor/bundle', 'public/system', 'public/uploads')set :rvm_ruby_version, '2.6.5'set :passenger_restart_with_touch, trueset :deploy_to, '/var/www/blog'set :use_sudo, true

and production.rb is

role :app, %w[deploy_user@ec2-13-232-140-179.ap-south-1.compute.amazonaws.com]role :web, %w[deploy_user@ec2-13-232-140-179.ap-south-1.compute.amazonaws.com]role :db,  %w[deploy_user@ec2-13-232-140-179.ap-south-1.compute.amazonaws.com]set :ssh_options, {  keys: %w[/d/Manna/Learning/RoR/EC2-Ubuntu.pem],  forward_agent: true,  user: 'deploy_user',  auth_methods: %w[publickey password]}

However, I am facing issues in authentication of deploy_user on EC2. I am able to SSH into EC2 using pem key. Here is the output when i try using "cap production deploy --trace"
