Laravel PHP. Error 419. What to do?

Question

Laravel

The tokens are the same on the LAN, but different on the hosting, because of this, error 419.
Host

LAN

Answer 1

csrf token, in theory, should always be unique (at least within one session), judging by the fact that the form has "return false;" on onsubmit, I can assume that the form is sent via ajax, check if the csrf token is sent.
Is the form sent to the same site?
Or are you trying to send a form from LAN to hosting? if so, then of course it will be 419, and csrf was invented for this.

Answer 2

Lord! I struggled with 419 error for a long time. In general, it is not written anywhere that the cache can be the cause. Clear all kinds of cache. Helped me.
Reoptimize loader class:
php artisan optimize
Clear facade cache:
php artisan cache:clear
Clear routes cache:
php artisan route:cache
Clear view cache:
php artisan view:clear
Clear config cache:
php artisan config:cache

Answer 3

I'll add my contribution!
I left the project for the night, and in the morning I sent an Ajax request and got the same error.
After F5 dropped to the login page.
That is, everything is simple - the token is gone, keep this in mind!

Answer 4

Another reason is session lifetime. If there is an auto login, authorization is not noticeable, but the token is re-created. Therefore, it remains either to extend the session while working with forms, or switch to API with Ajax.
