[Bug] Nominatim API 403

[Mason10198]

Hello! New Reitti user here, please educate me if I have missed something simple.

Installed Reitti via Proxmox Helper Script: https://community-scripts.org/scripts/reitti

Sending location info from Home Assistant into Reitti: https://github.com/myakove/reitti-HAIntegration

However, geocoding is not working due to 403 from Nominatim:

According to https://operations.osmfoundation.org/policies/nominatim/:

Requirements

• No heavy uses (an absolute maximum of 1 request per second).
• Provide a valid HTTP Referer or User-Agent identifying the application (stock User-Agents as set by http libraries will not do).
• Clearly display attribution as suitable for your medium.
• Data is provided under the ODbL license which requires to share alike (although small extractions are likely to be covered by fair usage / fair dealing).

Hi @Mason10198 ,

to test that, which version of reitti are you running? It is stated in Settings > About if unsure.

I was able to resolve the Nominatim issue by placing a user agent in the /etc/systemd/system/reitti.service Java command:

ExecStart=/usr/bin/java -Dhttp.agent="Reitti (name@email.com)" --enable-native-access=ALL-UNNAMED -jar -Xmx2g reitti.jar

I went to look for the version in the UI, but it unfortunately looks like my Reitti instance got stuck in a crash loop as soon as I enabled sharing from one user to another, and now I'm stuck and cannot access to UI at all :/

That is good to hear, I fixed that in the upcoming 4.0 release

Any error message? Then I will try to help resolve that. Never had that before.
