Browser Geolocation Permission Denied Fix

DodaTech Updated 2026-06-24 3 min read

In this tutorial, you'll learn about Browser Geolocation Permission Denied Fix. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

Browser geolocation uses GPS, WiFi, and IP data to determine user location. Permission denied errors occur when the user blocks location access, the browser is in private mode, or the site is not served over HTTPS.

The Wrong Way

navigator.geolocation.getCurrentPosition(
    (position) => {
        console.log("Lat:", position.coords.latitude);
        console.log("Lng:", position.coords.longitude);
    },
    (error) => {
        console.log("Error:", error);
    }
);

Output:

Error: GeolocationPositionError { code: 1, message: "User denied Geolocation" }

The Right Way

Request permission properly and provide fallbacks:

async function getLocation() {
    // Check if geolocation is available
    if (!navigator.geolocation) {
        console.log("Geolocation not supported");
        return null;
    }

    // Check permission state
    try {
        const permission = await navigator.permissions.query({name: "geolocation"});
        console.log("Permission state:", permission.state);
    } catch {
        // Permissions API not supported
    }

    return new Promise((resolve) => {
        const options = {
            enableHighAccuracy: true,
            timeout: 10000,
            maximumAge: 300000
        };

        navigator.geolocation.getCurrentPosition(
            (position) => {
                resolve({
                    lat: position.coords.latitude,
                    lng: position.coords.longitude,
                    accuracy: position.coords.accuracy
                });
            },
            (error) => {
                console.warn("Geolocation failed:", error.message);
                resolve(null); // Return null instead of crashing
            },
            options
        );
    });
}

// Use with fallback
async function getUserLocation() {
    const location = await getLocation();
    if (location) {
        console.log(`User at ${location.lat}, ${location.lng}`);
    } else {
        console.log("Using IP-based location as fallback");
        const ipLocation = await fetch("https://ipapi.co/json/").then(r => r.json());
        console.log(`IP location: ${ipLocation.city}, ${ipLocation.country}`);
    }
}

Step-by-Step Fix

1. Check HTTPS requirement

if (location.protocol !== "https:" && location.hostname !== "localhost") {
    console.warn("Geolocation requires HTTPS");
}

2. Request permission with user gesture

<button onclick="requestLocation()">Allow Location Access</button>

function requestLocation() {
    navigator.geolocation.getCurrentPosition(
        (pos) => console.log("Location:", pos.coords),
        (err) => console.log("Denied:", err.message)
    );
}

3. Handle permission changes

navigator.permissions.query({name: "geolocation"}).then(permission => {
    permission.onchange = () => {
        console.log("Permission changed to:", permission.state);
        if (permission.state === "granted") {
            getLocation();
        }
    };
});

4. Provide a manual location input fallback

<input type="text" id="manual-location" placeholder="Enter your city">
<button onclick="setManualLocation()">Set Location</button>

5. Use IP geolocation as fallback

async function ipGeolocation() {
    try {
        const response = await fetch("https://ipapi.co/json/");
        const data = await response.json();
        return {
            lat: data.latitude,
            lng: data.longitude,
            city: data.city
        };
    } catch {
        console.log("IP geolocation failed");
        return null;
    }
}

Prevention Tips

  • Always request geolocation in response to a user action (click, tap).
  • Explain why location is needed before requesting permission.
  • Provide a manual location input as fallback.
  • Use HTTPS for all pages that require geolocation.
  • Handle all error codes gracefully (permission denied, timeout, unavailable).

Common Mistakes with geolocation denied

  1. Using return to exit a function early instead of wrapping a pure value in the monad
  2. Mixing let bindings with <- bindings in do notation, producing type errors
  3. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors

These mistakes appear frequently in real-world BROWSER code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.

FAQ

### Why does geolocation fail in private browsing?

Some browsers restrict geolocation in private/incognito mode for privacy. The permission state may be set to "denied" by default, or the feature may be completely unavailable.

What does error code 1, 2, and 3 mean?

Code 1 (PERMISSION_DENIED): User blocked location. Code 2 (POSITION_UNAVAILABLE): GPS/WiFi could not determine location. Code 3 (TIMEOUT): Location request took too long.

How accurate is browser geolocation?

GPS provides accuracy within 5-20 meters outdoors. WiFi positioning provides 20-100 meters. IP geolocation provides city-level accuracy (1-50 km). Accuracy decreases indoors and in dense urban areas.
