Nominatim only indexes addresses of streets and then searches for
address nodes based on the address of the street they are attached
to.

In that particular example, the housenumber got attached to Hovedvegen
because Nominatim could not find a 'Ringvegen' and used the nearest
street:
https://nominatim.openstreetmap.org/ui/details.html?osmtype=N&osmid=3117603944

So you get a slightly different address than expected.
Fix the name of the street and everything sorts itself out.
