404 Not Found - Indexing Failed

Help and support
1

I have a self-hosted Nominatim installation. Everything was working fine until I started getting 404s for all Get requests. I noticed that indexing had failed. I ran the command “nominatim import --continue indexing” and ran the “testing the Nominatim service” command again and Indexing was now OK. But I’m still getting 404s.

Testing the Nominatim service

What version of Nominatim do you run? What does the log file for your Nominatim service say? What is the exact request that gets you a 404?

Nominatim version 5.1.0-0

nominatim search --query Berlin

works. It gives a JSON response.

curl -H “User-Agent: YourAppName/1.0 (your.email@example.com)” “http://localhost/nominatim/search?q=Berlin&format=json”

gives 404s.

Also, how do I increase logging levels and which logs specifically would that apply to?

Finally, would it make sense to just reindex everything? Is there a command for that?
