Laravel Socialite: InvalidStateException

Question

I\'m using Laravel Socialite to add a Facebook connect button on a website. Sometimes, I\'ve got this error on callback:

exception \'Laravel\\Socialite\\Two\         


        

Answer 1

I had a similar issue, I've got

InvalidStateException in AbstractProvider.php line 182

in the function handleProviderCallback() when it re-directs back from Facebook login. It seems to be the same as your issue.

Furthermore I found my issue occurs when I open my site without www. When I open my site with www.mysite.com - no problem. At first I think my issue is random until I've got the clue by Chris Townsend's reply to the question.

The Solution

Go to your www root, check the laravel file config/session.php. Check session Session Cookie Domain. The default configuration is 

'domain' => null,

I made a change to 

'domain' => 'mysite.com' 

After php artisan cache:clear and composer dump-autoload, I can login with no issue from both www.mysite.com and mysite.com
