Odoo closes user sessions every time

[specks-zz]

Impacted versions: 13 Community

Hi, I need help.

In my company we have deployed Odoo 13 Community.

In the las 2 months we have problems in the longpolling configuration,
this has caused sessions to be closed every time.
In the firefox logs i see that when the poll connection failed the session are closed (hcm_ciberc is the database name)

In the server log i see many logs from longpolling, this is normal??

This is my odoo-server.conf configuration

And this is the configuration in nginx from my site.

The red marks indicate the parameters that I have added following guides from various posts

In postgres.conf in postgres I also applied several improvements suggested in this post
https://www.odoo.com/es_ES/forum/ayuda-1/odoo-server-and-postgresql-optimization-158168

But nothing works properly

My server’s configuration are:
Ubuntu Server 20
32 GB Ram
1 TB HDD
8 Cpu’s Cores
The datadase is hosted in another server with the same configuration.
Please guide me to apply a correct configuration

Regards.

Hi.
I'm not sure if that is the case, I mean, I've validated with the users that use the system the most, however they are in several countries so it is difficult to know if that is the problem.
I have reviewed the system logs and and querying in postgres i saw that reaching 105 or more transactions is when the sessions begin to close:

At the moment I have removed the option of the workers in odoo.conf, now it shows an alert however the sessions are not closed.
