Hi all.

I'm having an Odoo 18 running in docker. All works fine, except the subject issue. I'm stuck, because all real-time services seems to be working - user status updates, chat (I see that someone is typing a message to me when chat is open), notifications, etc. All except the kanban real-time update.

I have following configs (according to best practices, as I'm concerned 🙂):

docker-compose:
