I already try some answers on the internet to stop Odoo that running on my Ubuntu server, but it didn't work. I run Odoo by using this command from the root Odoo folder

python3 odoo-bin -c odoo.conf

If I run this command again using another session after Odoo is running, I get this kind of error message

Exception in thread odoo.service.httpd:
Traceback (most recent call last):
...
...
OSError: [Errno 98] Address already in use

When I list all services that run on my server, there is no Odoo service running, but when I open the domain, I know the Odoo server is running.
