If a shared Maptitude Online map does not load correctly, your browser or organization’s network may be blocking access to one of the domains required to display the map. This can cause some map layers, labels, colors, or detailed geography such as states, counties, ZIP Codes, or census tracts to appear incorrectly or not appear at all.
This issue may occur when the map works for some users but not for others. For example, a shared public map may open successfully on one computer or network, while another user sees a missing layer message or a map that only loads partially. In many cases, the issue is caused by a firewall, proxy, browser extension, or security setting that prevents Maptitude Online map content from loading. To fix this, your IT department may need to whitelist the required Maptitude Online domains.

Symptoms of a Blocked Shared Map
A shared Maptitude Online map may be blocked by a firewall, browser setting, or network filter if you see any of the following issues:
- The map opens, but one or more layers do not draw.
- A color theme, map style, or label layer is missing.
- The map works for some users, but not for others.
- The map works for one computer or network, but not for others.
- An error appears saying that a map layer is missing a data source.
- The browser console shows failed map, tile, or data loading requests.
Whitelist the Required Maptitude Online Domains
If you are on a company, school, government, or other managed network, ask your IT department or network administrator to whitelist the following Maptitude Online domains:
These domains are used to open Maptitude Online maps and display map tiles, vector tiles, and other map content. If one of these domains is blocked by a firewall, proxy, web filter, browser extension, or security setting, a public shared map may open only partially.
After the domains are whitelisted, try opening the shared map again. If possible, test the same shared map from another network, such as a mobile hotspot, to confirm whether the issue is specific to your organization’s network.
Try Browser Troubleshooting Steps
If the required domains are whitelisted but the map still does not load correctly, try these browser troubleshooting steps:
- Refresh the shared map page.
- Open the shared map in a private or incognito browser window.
- Try a different supported browser.
- Disable browser extensions that block scripts, ads, tracking, or network requests.
- Clear the browser cache and reload the map.
Browser extensions and security tools can sometimes block map data even when the network itself allows the required domains.
