Map Tiles Are Not Loading

What to check when the GPS map is blank.

Use this when

The GPS map panel shows your track line but the background map is blank, grey, or shows broken tile squares.

Common reasons

  • No internet connection — HumVision fetches map tiles live from external tile servers. There is no built-in offline cache.
  • MapTiler tile styles require an API key — Street Map, Outdoor Map, Adaptive Map, Satellite with Labels, and Hybrid all call the MapTiler API. If the app was built without a valid key, those styles return no tiles.
  • Tile server is temporarily down — Carto, MapTiler, OpenStreetMap, ESRI (Satellite), and OpenTopoMap are separate services. Any one of them can be unavailable for short periods.
  • Firewall or proxy is blocking tile requests — Corporate or school networks sometimes block requests to CDN hostnames like basemaps.cartocdn.com, api.maptiler.com, or tile.openstreetmap.org.
  • Map container did not resize — Collapsing the sidebar can leave blank strips at the edge until the map repaints.

How to check

  1. Open any web browser on the same machine and load https://www.openstreetmap.org. If that page fails, the problem is your internet connection, not the app.
  2. Note which map style is selected in Settings > Map Style. If it is anything other than Clean Map or OpenStreetMap, it uses the MapTiler API.
  3. Open the app's developer console (View > Toggle Developer Tools on Windows/Linux, or via the menu on macOS) and look for network errors on requests to tile server hostnames.

What to try next

  1. Switch to Clean Map in Settings > Map Style. Clean Map uses the Carto CDN and does not need a MapTiler key. OpenStreetMap is a second key-free fallback.
  2. Check your network connection and retry. Reconnect Wi-Fi or switch from a metered connection to a faster one.
  3. If you are on a corporate network, ask your IT team to allow outbound HTTPS to *.cartocdn.com, *.maptiler.com, *.tile.openstreetmap.org, and server.arcgisonline.com.
  4. Try collapsing and expanding the sidebar. This forces the map to repaint the full viewport.
  5. Restart the app. A stale tile request can occasionally block new ones.

If it still does not work

If tiles fail for all styles on a working internet connection, contact support at support@gethumvision.com and include the network errors from the developer console.
