ERR\_TOO\_MANY\_REDIRECTS (redirect loop)
=========================================

### [\#Errors](https://rocketeersapp.com/knowledge/errors)

This error means the browser was bounced between URLs until it gave up. The classic cause is a redirect loop between HTTP and HTTPS, very often a Cloudflare SSL setting fighting your server config.

[\#](#content-about-the-error "Permalink")About the error
---------------------------------------------------------

The browser shows `ERR_TOO_MANY_REDIRECTS` (Chrome) or "The page isn't redirecting properly" (Firefox). It means a URL redirected to another URL that redirected back, forming a loop. After a handful of hops the browser stops to avoid looping forever.

[\#](#content-why-do-i-see-this-error "Permalink")Why do I see this error
-------------------------------------------------------------------------

The overwhelmingly common cause is an **HTTP ↔ HTTPS loop**, and the most common trigger of that is **Cloudflare's SSL mode set to "Flexible"**:

- Cloudflare talks to your server over plain HTTP.
- Your server (or app) redirects all HTTP to HTTPS.
- Cloudflare receives that redirect, requests again over HTTP, gets redirected again, forever.

Other causes: an app forcing HTTPS while a proxy already terminates TLS, a misconfigured `www` ↔ non-`www` redirect, or two redirect rules pointing at each other.

[\#](#content-solution "Permalink")Solution
-------------------------------------------

### [\#](#content-fix-cloudflare-ssl-mode "Permalink")Fix Cloudflare SSL mode

If you use Cloudflare, set the SSL/TLS encryption mode to **Full** or **Full (strict)**, never **Flexible**. Flexible is the single biggest cause of this loop for sites behind Cloudflare. Full means Cloudflare connects to your origin over HTTPS, which matches your server redirecting to HTTPS. See [an A+ grade SSL using Cloudflare](/a-plus-grade-ssl-using-cloudflare).

### [\#](#content-trust-the-proxys-protocol-header "Permalink")Trust the proxy's protocol header

When TLS is terminated by a proxy or load balancer, your app sees the request as plain HTTP and redirects to HTTPS, even though the visitor is already on HTTPS. Tell the app to trust the forwarded protocol. In Laravel, configure trusted proxies in `bootstrap/app.php`:

 ```
->withMiddleware(function (Middleware $middleware) {
    $middleware->trustProxies(at: '*', headers:
        Request::HEADER_X_FORWARDED_FOR |
        Request::HEADER_X_FORWARDED_HOST |
        Request::HEADER_X_FORWARDED_PORT |
        Request::HEADER_X_FORWARDED_PROTO
    );
})

```

### [\#](#content-check-your-nginx-redirect "Permalink")Check your nginx redirect

A correct HTTP→HTTPS redirect redirects only plain HTTP, and the HTTPS server block must not redirect again:

 ```
server {
    listen 80;
    server_name example.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name example.com;
    # serve the site here, do NOT redirect to https again
}

```

### [\#](#content-diagnose-the-loop "Permalink")Diagnose the loop

Follow the redirect chain from the command line to see exactly where it loops:

 ```
curl -sIL https://example.com | grep -i location

```

If you see the same two URLs alternating, you've found your loop.
