Odoo - no process is listening on long polling port + possible solution

Question

Have started a new Odoo server on Ubuntu Linux. Used a script by Yenthe Van Ginekken (probably the most popular one):

sudo wget https://raw.githubusercontent.com/Yenthe666/InstallScript/11.0/odoo_install.sh

No fancy modules. After installing SSL cert(using Certbot) I realised that Discuss & Chat apps are not working. So I updated my config (workers=4, proxy mode is true) as well as Nginx config.

Odoo config:

[options]
addons_path = /odoo/odoo-server/addons,/odoo/custom/addons
admin_passwd = pwd
csv_internal_sep = ,
data_dir = /odoo/.local/share/Odoo

Nginx:

#odoo server
upstream odoo {
 server 127.0.0.1:8070;
}
upstream odoochat {
 server 127.0.0.1:8072;
}

server {
   listen 80;
   server_name www.onet.pl;
   rewrite ^(.*) https://$host$1 permanent;
}

server {
 listen 443;
 server_name www.onet.pl;
 proxy_read_timeout 720s;
 proxy_connect_timeout 720s;
 proxy_send_timeout 720s;

 # Add Headers for odoo proxy mode

 proxy_set_header X-Forwarded-Proto $scheme;
 proxy_set_header X-Real-IP $remote_addr;

 # 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;
 }

location ~*  \.(jpg|jpeg|png|gif|ico|css|js)$ {
proxy_pass http://odoo;

expires 365d;
    }
 # common gzip
 gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
 gzip on;
}

The weird thing is that when I check the 8072 port(using lsof -i :8072) nothing is listening there...

Ok, I have spent some time on it and got a solution. Haven't really found the answer why long polling was not working with the proper settings - that is why I am going to leave the question open.

I have basically replaced the original nginx config with the simple proxy reverse config without HTTPS:

server {

    listen 80;

    server_name http://yoursite.com;

     location / {

proxy_pass http://0.0.0.0:8069;

proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Forwarded-Proto $scheme;

proxy_read_timeout 3000000;

client_max_body_size 2000M;

}

# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

}

Then I simply used Certbot (https://certbot.eff.org/) and choose the option to redirect(that is the last point). Config generated by Certbot looks different but it works. Will test it on Monday on a different website and produce a tutorial.
