Odoo 11 Nginx Reverse Proxy Index of / - nginx

Question

I have a odoo 11 installation behind a Nginx proxy. Its been working for a while but now when you access it, its showing index of / instead of Odoo login page (see screenshot).
Here is my Nginx configuration:
#odoo server
upstream odoo {
server 127.0.0.1:8069;
}
upstream odoochat {
server 127.0.0.1:8072;
}
# http -> https
server {
listen 80;
server_name businessapps.enone.tech;
#server_name odoo;
rewrite ^(.*) https://$host$1 permanent;
}
server {
listen 443;
server_name businessapps.enone.tech;
#server_name odoo;
proxy_read_timeout 720s;
proxy_connect_timeout 720s;
proxy_send_timeout 720s;
# Add Headers for odoo proxy mode
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Real-IP $remote_addr;
# SSL parameters
ssl on;
ssl_certificate /etc/letsencrypt/live/businessapps.enone.tech/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/businessapps.enone.tech/privkey.pem;
ssl_session_timeout 30m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers '<replaced cipher>';
ssl_prefer_server_ciphers on;
# log
access_log /var/log/nginx/odoo.access.log;
error_log /var/log/nginx/odoo.error.log;
# Redirect longpoll requests to odoo longpolling port
location /longpolling {
proxy_pass http://odoochat;
}
# Redirect requests to odoo backend server
location / {
proxy_redirect off;
proxy_pass http://odoo;
}
# common gzip
gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
gzip on;
}
Can someone point out what could be the issue. Sometimes I can access the login page, other times I get the index of / page. The installation is on Ubuntu 16.0

Answer 1

You need to specify the directory in the nginx config, and I had this error previously and found that even once changing my config I had weird errors with odoo, so I recommend you do what I did and that is completely re install Nginx and ensure you reboot your server after having done so!

Answer 2

Add location block inside server {} (block)
I have used below nginx configuration
upstream odooapp {
server odoo:8069;
keepalive 8;
}
upstream longpolling {
server odoo:8072;
keepalive 8;
}
server {
listen 80;
listen [::]:80;
server_name businessapps.enone.tech;
access_log /var/log/nginx/access.log mainlog;
error_log /var/log/nginx/error.log;
return 301 https://businessapps.enone.tech:443/web/login;
}
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name businessapps.enone.tech;
access_log /var/log/nginx/access.log mainlog;
error_log /var/log/nginx/error.log;
ssl_ciphers ALL:!ADH:!MD5:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_certificate <PATH_TO_CERT>;
ssl_certificate_key <PATH_TO_KEY>;
add_header Strict-Transport-Security "max-age=2592000; preload;" always;
location / {

proxy_set_header X-NginX-Proxy true;

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_connect_timeout 300;

}
location /longpolling {
