我怎么能在关于子域的laravel中修复这个错误

I use a test domain in laravel and one subdomain is in use. Everything works fine,

test.com and user.test.com

but, Login function does not work on test domain

I have verified that the session file is generated at stoage / sessions

when I done login, it does not cognize my session. The login function works well on localhost url. how i can fix that?

i'm done config like this below

config / session.php 
domain => ".test.com"

And if I set up like above, can I share login information between two domains?

Clear the cookies for the site and then try to log in again. Or If the issue still persists then try to change Session Cookie Name in config/session.php
