conncheck.opensuse.org

Looking at the list of queries (permitted domains) on my pi-hole, I noticed a repetitive query from the leap 15.2 operating system running on my pc to conncheck.opensuse.org. Like to know the function of the query and why it is needed by leap 15.2. I have not seen this type of inquiry in other distros.

It is NetworlManager checking if there is a connection to the internet.

See also the discussion here where there are also hints on how to switch it off.
