Hi everybody! I'm struggling with an 500 HTTP error fired by the polling proccess (used for chat messages) -as far as I can understand, beacuse the polling proccess can't connect to PostgreSQL (but Odoo main process can, though).

Symptom

Everything in Odoo works just fine, except ONLY for the IM: randomly and after some hours or even days, messagges doesn't refresh automatically and Odoo accuses of losing connection and getting it back automatically (sometimes the session even expires).

No IM message is lost: refreshing the webpage shows the latest IM messages.

Enviroment

• VM witth 4 virtual processors and 16 GB of RAM

• Ubuntu 20.04

• Odoo 14 Community Edition

• NGINX as a reverse proxy

Logs

I managed myself to set all logs to debug mode, and I found that the longpolling process is trying to connect to database "postgress", when my only database is called "odoo". I couldn't find where that could be setted (as I have in my odoo.conf, db_name = odoo)

This is the Odoo log in debug mode:

Question

Can anybody help me with this issue? Is it with workers or db-connection oriented issue? Any idea will help.

Thanks!
