Troubleshooting-Error-419-Page-Expired

Overview​

Error 419 - Page Expired in Laravel typically occurs due to issues with session or CSRF token validation. One of the most common causes is a mismatch between the browser URL and your environment (.env) configuration.

✅ Verify .env Configuration​

Ensure the following .env values match exactly what you are entering in the browser (including http vs https, subdomains, and ports):

APP_URL=https://your.domain.com
SESSION_DOMAIN=.your.domain.com
SANCTUM_STATEFUL_DOMAINS=your.domain.com

Tips​

  • Use a dot-prefixed domain (e.g., .your.domain.com) for SESSION_DOMAIN if you're using subdomains.

  • Don't include http:// or https:// in SANCTUM_STATEFUL_DOMAINS.

  • APP_URL must include the scheme (http or https).

🧼 Clear and Cache Config​

After updating the .env file, run the following command to apply changes:

php artisan config:cache

🧪 Test It​

  1. Clear your browser cookies and cache (especially relevant for SESSION_DOMAIN changes).

  2. Refresh the page or retry the action that triggered the 419 error.

🛑 Still Seeing 419?​

Double-check:

  • If you're running the app in a Docker container, ensure .env and actual host URL match.

  • If you're using HTTPS, ensure the certificate is trusted and valid.

  • Check your browser dev tools > Cookies to confirm session cookies are being sent.

📌 Quick Example​

If you're accessing the app using https://fs-pbx.example.com, then:

APP_URL=https://fs-pbx.example.com
SESSION_DOMAIN=.example.com
SANCTUM_STATEFUL_DOMAINS=fs-pbx.example.com
