Laravel 5.5 login not working on PRODUCTION

I put my Laravel 5.5 project on production server. And my Login isn't working...

1. I did key:generate
2. Then migrate
3. Then db:seed
4. password was with bcrypt()

On localhost everything is working just fine. I didn't change anything in Auth controllers, my login form has csrf_field.

The only difference between localhost and production is, that I did composer install in november on localhost and composer install today on production.

Can anyone please help me, or having similar issue? I haven't find answers anywhere...
