NGINX not serving CSS, Images and other media files - css

Question

I have installed NGINX on my ubuntu 16.04 LTS server to satisfy the need to navigate to different applications on the same linux server.
So I have installed it and followed this tutorial : https://www.youtube.com/watch?v=PTmFbYG0hK4&t=677s
I defined it exactly as the tutorial shows but I ran into a problem where the NGINX not serving any media files for a specific application (CSS, Images, stylesheets etc). I will be clearer: I defined inside sites-available a configuration file as such (of course I made a symbolic link to the sites-enabled directory.):
server{
listen 80;
listen 443 ssl;
location / {
root /home/agent/lexicala;
}
location /test {
proxy_pass "http://127.0.0.1:5000";
rewrite ^/test(.*) $1 break;
}}
The "location /" - serving my HTML files and website perfectly.
But when I try to approach to "MyServersIP/test/" (serving a node app) which supposed to be served from "location /test" - the routing is good but NGINX serving it without any media.
On the chrome console I have inspected it in chrome and see the following errors:
GET http://MyServersIP/stylesheets/style.css net::ERR_ABORTED
GET http://MyServersIP/scripts/jquery.multiselect.js net::ERR_ABORTED
GET http://MyServersIP/css/jquery.multiselect.css net::ERR_ABORTED
I have tried to follow posts which I saw that people ran into the same problem:
Nginx fails to load css files ;
https://superuser.com/questions/923237/nginx-cannot-serve-css-files-because-of-mime-type-error ; https://www.digitalocean.com/community/questions/css-files-not-interpreted-by-the-client-s-browser-i-think-my-nginx-config-is-not-good
And many more, but nothing worked for me.
Another thing worth mentioning - when I swap routings like this:
server{
listen 80;
listen 443 ssl;
location / {
proxy_pass "http://127.0.0.1:5000";
}
location /test {
root /home/agent/lexicala;
rewrite ^/test(.*) $1 break;
}}
The node app is served perfectly, but it is not good for me as I want the users to approach my node app through the 'test' URL.
This is my nginx.conf file (I have made no changes):
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}

}
I tried to supply as much details as I could but if something is missing I would be glad to add.
Hope you guys help me find solution to this bug cause I spend over it good working days.
