Issue
I am facing Token mismatch exception in Laravel 5.4 on live server. On my local machine running Windows XAMPP, the application works fine. When I deployed it to live machine running CENTOS 7 and LAMP stack, I see a redirecting to myhostname.com/login at the top left corner of the browser and then lands on an error page showing:
token mismatch exception on line 68 of VerifyCsrfToken.php.
Solution
I had this same problem and what i did was:
First in your .env file remove: SESSION_DOMAIN
And in set session driver like: SESSION_DRIVER=file (if your want it to save to a file)
then do: php artisan cache:clear
then `php artisan config:clear
that worked for me.
