What am I doing wrong?

I'm surprised you got the response

  "osm_type": "relation",
  "osm_id": 2255630,

because that relation was deleted 11 years ago. https://www.openstreetmap.org/relation/2255630/history/

Is there any chance you're connecting to an old Nominatim installation or database?

I don't think so, because https://ftp5.gwdg.de/pub/misc/openstreetmap/planet.openstreetmap.org/pbf/ source is approved as native source of data and i always get last data
