everything works perfectly and super fast, but then I tried other countries I hadn’t imported, and still it works?
I shut down my client pc internet connection, and nothing worked, not even the imported map from austria, just grey squares
the webserver performs queries in the database, I checked this, no error messages
so am I required to have an internet connection, and is it possible to turn that off?
I try to get your wording straight so you can communicate more effectively in the OSM ecosystem in the future. Please ignore this post if it sounds too pedantic.
You imported OSM data (or “an OSM dump”), not “maps”. Maps are images of something. You didn’t import an image to your database
There may be confusion on what exactly “works”, and how.
What you mean (probably) is that you both can view a map and can geocode addresses.
“nothing works” may be a misunderstanding: you do not see a map, because map tiles are not accessible, because you have no internet connection. But the geocoding part of nominatim should still work.
