Hello,

I installed WordPress with one-click app and was following this tutorial:
https://www.digitalocean.com/community/tutorials/how-to-configure-nginx-as-a-web-server-and-reverse-proxy-for-apache-on-one-ubuntu-16-04-server#step-1-—-installing-apache-and-php-fpm

..and I'm stuck at Step 4, can not see can not see php_info file.

Here's the log.

I think the one-click installation has firewall enabled by default. Please run this command:

sudo ufw status

    @c132 @hansen

    The one-click I deployed yesterday when troubleshooting the Apache configurations you and I were working on did indeed have ufw enabled by default, so port 8080 would need to be added to the rule set using:

    sudo ufw allow 8080/tcp

    If that still doesn't work, we'd need to see the configuration in full so we can take a look at it and see if there's anything that needs to be fixed to get everything in working order.
