HA constantly communicating with checkonline.home-assistant.io

Hi,
Just found out on my Mikrotik router that my Homeassistant is constantly communicating with checkonline.home-assistant.io.
It just keeps going on and on and eating my LTE traffic non stop.
What’s wrong here?
Is it normal?
And, why is it doing it constantly?
What should I check?

Searching can do miracles

How to throttle Supervisor’s version check? - Configuration - Home Assistant Community (home-assistant.io)

Yep, I found it earlier but didn’t gave me the right answer or remedy…
Or did I missed something?
I’m not very familiar with the NM, as everything I do is thru HA, sometimes terminal and that’s it.

Yes, it’s normal.
