Other locations saved non-volatile

Few other locations had been added manually to ~/.config/gtk-3.0/servers as adding them all through nautilus gui is cumbersome.
The expectation is Nautilus' GUI - Other locations > Connect to server - shows the list of locations stored to file.
In gui that list is however empty.

How to fix it?
Which role has mentioned file and one other: ~/.config/nautilus/servers?
