Changes required on nginx default or nginx's conf file.

Add below  code under section where your are Redirecting requests to odoo backend server 

====================== Syntax ===================================

 location / {

   proxy_pass http://odooapplicationurl:port;

   proxy_redirect http://odooapplicationurl:port/ https://yourapplicationdomain/;

   proxy_set_header X-Real-IP $remote_addr;

   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

 }

 ============================ Example ================================

   location / {

   proxy_pass http://192.168.0.1:8069;

   proxy_redirect http://192.168.0.1:8069/ https://mycompanyodoo.com/;

   proxy_set_header X-Real-IP $remote_addr;

   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

 }

========================== Justification ===================================

Odoo logout controller returns 301 http code.

Nginx require below headers in conf file when 301 http code return by application else odoo application will show bad request 400.

   proxy_set_header X-Real-IP $remote_addr;

   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
