Fix Laravel Reverb WebSocket ERR_CONNECTION_REFUSED Error

Fixing the WebSocket connection refused error in Laravel Reverb during local development boils down to properly configuring self-signed certificates from mkcert, aligning your .env ports and schemes, and ensuring Reverb serves TLS on port 8080. Mismatches between broadcasting.php defaults, reverb.php SSL paths, and Herd’s HTTPS setup often cause ERR_CONNECTION_REFUSED on wss://docuvault.test:8080. Follow these steps to get real-time events flowing smoothly without proxy headaches.

Understanding the Laravel Reverb WebSocket Error

That net::ERR_CONNECTION_REFUSED on wss://docuvault.test:8080? It’s Laravel Reverb’s way of saying, “I can’t establish a secure WebSocket handshake.” Your setup looks solid at first glance—Herd handling HTTPS, mkcert certs in place—but subtle mismatches kill it. Reverb needs to serve TLS itself on 8080, not just expect the client to connect securely.

Why port 8080 specifically? Reverb defaults to it for TLS to avoid clashing with your app’s 443. Browsers demand a trusted cert for wss://, and self-signed ones from mkcert work great if the root CA is installed. But if Reverb chokes on loading your docuvault.test.pem, or Herd blocks the upgrade, boom—refused.

Users on GitHub issues report the exact same: Echo tries wss://, but Reverb isn’t listening with TLS enabled. Let’s fix it step by step.

Step 1: Verify mkcert Certificates

First things first: your certs. Run mkcert docuvault.test again to confirm.

mkcert docuvault.test

This spits out docuvault.test.pem and docuvault.test-key.pem in your project root. Install mkcert’s root CA if you haven’t: mkcert -install. Your browser must trust this, or it’ll reject even valid self-signed certs.

Test the cert standalone:

openssl x509 -in docuvault.test.pem -text -noout

Look for Subject: CN=docuvault.test. Mismatch here? Regenerate. Place them exactly at project root—no subfolders—since your reverb.php uses base_path('docuvault.test.pem').

Pro tip: Herd users often forget mkcert roots aren’t global. Restart your browser after install. Still refused? Cert paths are next.

Step 2: Update .env for HTTPS Reverb

Your .env is close, but let’s lock it down. Laravel Reverb expects consistency across host, port, and scheme.

APP_URL=https://docuvault.test
REVERB_APP_ID=214918
REVERB_APP_KEY=ymstb1nglumzbxm9yjoq
REVERB_APP_SECRET=qx9smxoms8smr5repkcf
REVERB_HOST=docuvault.test
REVERB_PORT=8080
REVERB_SCHEME=https
REVERB_SERVER_HOST=127.0.0.1 # Add this—binds Reverb internally, skips domain cert woes

That REVERB_SERVER_HOST=127.0.0.1 is a game-changer for local setups like Herd or Valet, as noted in this GitHub thread. Reverb listens on localhost:8080 with your certs, but advertises as docuvault.test:8080 to clients.

Clear config cache: php artisan config:clear. Restart Reverb: php artisan reverb:restart --debug. Watch for “Reverb server started on 127.0.0.1:8080” and no SSL load errors.

Step 3: Configure reverb.php SSL Correctly

Your reverb.php apps section is mostly right, but tweak for reliability. Here’s the polished version:

'apps' => [
 [
 'key' => env('REVERB_APP_KEY'),
 'secret' => env('REVERB_APP_SECRET'),
 'app_id' => env('REVERB_APP_ID'),
 'options' => [
 'host' => env('REVERB_HOST'),
 'port' => env('REVERB_PORT', 8080),
 'scheme' => env('REVERB_SCHEME', 'https'),
 'ssl' => [
 'local_cert' => base_path('docuvault.test.pem'),
 'local_pk' => base_path('docuvault.test-key.pem'),
 'verify_peer' => false, // Add for self-signed leniency
 'allow_self_signed' => true,
 ],
 'useTLS' => true,
 ],
 // ... rest unchanged
 ],
],

Pulling from Stack Overflow’s detailed fix, these extra SSL options prevent Reverb from rejecting its own cert. verify_peer => false is local-dev only—don’t ship it.

php artisan config:cache after changes. Fire up Reverb and tail logs: tail -f storage/logs/laravel.log. Expect “TLS enabled” vibes, no cert errors.

Step 4: Align broadcasting.php Client Connection

Broadcasting.php’s default port=443 overrides your .env if unset—sneaky! Update to match:

'reverb' => [
 'driver' => 'reverb',
 'key' => env('REVERB_APP_KEY'),
 'secret' => env('REVERB_APP_SECRET'),
 'app_id' => env('REVERB_APP_ID'),
 'options' => [
 'host' => env('REVERB_HOST'),
 'port' => env('REVERB_PORT', 8080), // Changed default to 8080
 'scheme' => env('REVERB_SCHEME', 'https'),
 'useTLS' => env('REVERB_SCHEME') === 'https',
 ],
 'client_options' => [
 'verify' => false, // Guzzle: Skip SSL verify for local self-signed
 ],
],

The client_options bit tells Echo’s Guzzle client to chill on cert validation, fixing client-side refusals per this issue. Test in browser console: Echo should connect without net::ERR_CERT_AUTHORITY_INVALID.

Step 5: Handle Herd Proxying for WebSockets

Herd shines for HTTPS, but WebSockets on 8080 need proxy love. Herd doesn’t auto-upgrade WS by default. Add a custom Nginx site or use Herd’s proxy features.

In Herd, edit ~/.config/herd/sites/docuvault.test/nginx (or create if missing):

server {
 # ... Herd's defaults ...
 location /app/ { # Match your app path from error
 proxy_pass http://127.0.0.1:8080;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "Upgrade";
 proxy_set_header Host $host;
 proxy_cache_bypass $http_upgrade;
 }
}

Restart Herd: herd reload. This proxies wss://docuvault.test/app/... to Reverb’s 8080, forwarding upgrades. From Nginx configs in issues, this nails production-like local setups.

Firewall check: lsof -i :8080—Reverb should own it. macOS firewall? Temporarily disable.

Troubleshooting Persistent Issues

Still refused? Here’s the hit list:

• Logs first: php artisan reverb:start --debug. Cert load fails? Paths wrong.
• Browser incognito: Clears cached bad certs.
• Port conflict: netstat -an | grep 8080. Kill squatters.
• Echo JS: In resources/js/bootstrap.js, force Echo.connector.reverb.options.scheme = 'https';.
• Herd quirk: Set REVERB_HOST=localhost temporarily—tests if domain resolution flakes.

Conclusion

Mastering Laravel Reverb’s WebSocket connection refused error locally means nailing cert trust, port alignment, and proxy upgrades—your setup should hum now with secure real-time broadcasts. Key wins: mkcert roots installed, REVERB_SERVER_HOST=127.0.0.1, SSL options relaxed, and Herd proxy in place. Test by dispatching an event; if Echo connects green, you’re golden. Scale this to prod by swapping self-signed for real certs. Happy broadcasting!
