Problem Installing PufferPanel OVH Ubuntu 16.04

[AdamW78]

Hi there,
I started trying to install PufferPanel on my VPS last night, but I keep getting an error. I thought I had everything set up, but when I go to my site, I get a bad gateway (502) error. I am running nginx and when I type systemctl status nginx, I get this output to the console:

When I run systemctl status pufferd, I get this output:

My srv/pufferpanel/logs folder is completely empty, but during the install, I get this error:

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'pufferpanel'@'localhost' (using password: YES)

I'm not sure why I'm getting this error. Originally, I installed this set up with root and the root MySQL password. I then uninstalled by deleting srv, deleting var/lib/pufferd, and deleting etc/pufferd. I reinstalled after creating a MySQL user with the name pufferpanel and using that password in the installer. Still got the same errors. I have setup my pufferpanel.conf file in pool.d and changed the listen port to 127.0.0.1:9000 or whatever it's supposed to be.

Any ideas? Thanks!

Why did you change the listen port to 9000?

[AdamW78]

Change the listen port to 9000 in what? In the /etc/php/7.0/fpm/pool.d/www.conf file? Because if so, then yes, I did.

EDIT: If I add :5656 to the end of the web address in my bar, this displays in the browser:
{"success":true,"msg":"pufferd is running"}
:5657 Sends an invalid http response.

@AdamW78 You shouldn't have needed to change that. What happens if you tried to revert the www.conf before the changes?

[AdamW78]

Same problem if I revert it.

Does nginx work normally if you remove the pufferpanel.conf from /etc/nginx/sites-enabled?

[AdamW78]

@Nystrata Yes. If I remove the pufferpanel.conf, I get this page:
