Memcached – Laravel session doesn't work for other sub-domains

I have a problem with the session in Laravel 5.3.

For our project, we have 2 sub-domain :

• 1 for developement’s environment
• 1 for preproduction’s environment

for the first sub-domain no problem, it all works. But the second sub-domain nothing works. I concluded that the problem is the session, because on my second sub-domain, none cookies created.

I have look my session’s file in my config and update any datas. This is my config session’s file :

<?php

return [

/*

| Default Session Driver

|
| This option controls the default session "driver" that will be used on

| you may specify any of the other wonderful drivers provided here.
|
| Supported: "file", "cookie", "database", "apc",
|            "memcached", "redis", "array"
|
*/

I don’t found a solution despite much search,

Thanks

I found the solution, my problem came from a bad configuration of the cloud front and not of laravel. Thanks at all for your help
