No notification dot on bell icon, until page refresh

[Emmker]

Hi. When a user gets a new notification, the bell icon at the upper right does not get the "1" dot sign, but when I click on the bell the notification shows in the popup menu.
The notification dot is not showing if I navigate to another menu either.
The only way to reveal the notification dot is to refresh the page.
Is that the normal behaviour?
Is there something that I can do to have the dot show up immediately?

Maybe you enabled WebSocket in the settings but did not set up it on the server.

My webscocket is enabled and configured properly, but I still get the: WebSocket connection to 'wss://mydomain/wss?authToken="authtoken"&userId=1' failed:

I am connecting to the espocrm through a cloudflare tunnel. Could it be that there is a problem with the way cloudflare handles the websocket requests?

UPDATE

There was no problem neither with cloudflare nor with my settings.
The problem was that I had a file browser installed listening to 8080 port and the websocket could not work because of that.
