ERP NEXT install facing issues

Hi all,
I have installed new erpnext in digital ocean with ubuntu server. I faced some problems while installing it.
now i have installed to latest version. but its now working on the browser. i don’t know where its gone wrong.
TERMINAL CODE:

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: pip install frappe-bench

erpnext 12.11.2
frappe 12.9.1

My install erpnext and frappe version in path /opt/bench/frappe-bench.

root@ERP-Next-venpep-careers:/opt/bench/frappe-bench# bench restart
WARN: bench is installed in editable mode!

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: pip install frappe-bench

$ supervisorctl restart frappe-bench-workers: frappe-bench-web:

Also services are also enabled.

root@ERP-Next-venpep-careers:~# systemctl list-unit-files | grep ‘fail2ban|nginx|supervisor’
fail2ban.service enabled
nginx.service enabled
supervisor.service enabled

What else i have to configure to make it visible
when loading ip on browser it shows “This site can’t be reached”

Did you install frappe in production mode?

You might try reaching the site under http(s)://<yourdomain>:8000

hi @Sebastian
thanks for your reply.

I tried using port. its also showing nginx server page.

Also when i try to install using production setup via install.py it shows this error

subprocess.CalledProcessError: Command '['ansible-playbook', '-c', 'local', 'site.yml', '-vvvv', '-e', '@/tmp/extra_vars.json', '--become', '--become-user=frappe']' returned non-zero exit status 2.
