Sounds like session is not being written. Are you sure your storage permissions are correct.
Page Expired 419 on shared hosting
I have a popular problem trying to fix it for two days, but with no progress. It seams that it appear while uploading project to host. It show that Page expire 419, and every time I login it create a new session in (storage/framework/sessions) directory. I have tried many solutions following this issue in stack overflow and many others. I have tried to avoid CSRF Token by giving $except var my login route and it's continue progress without page expired but with a blank page only "Redirecting to .. {home}" without passing login method in controller.
Finally after many search I found solution in stack-over flow , Inside your main index.php file inside public folder, edit it and at the very top write ob_start()
