The default ones are .conf, the other one that I use for odoo is not, I named it only "odoo".
I had already tried with the name of odoo.conf and it did not work either
Please show us where the files are.
Note: Nginx only loads web host config files from /etc/nginx/sites-enabled/, is this the place you store config files for odoo web host?
When you run "nginx -t", does it report any error?
