Distance matrix - the search graph could not be calculated completely

This is a warning message, not an error.
It should be pointed out to the user that one or more points (sites) could not be connected to the road network [it depends on the routing profile so you can see this message for the same site multiple times].
Within the message box, the user can use the Details button to display a list of positions.
Digits whose number of uncalculated relations is greater than two must be checked.
