Sessions Not Persisting

I've been searching and searching for an answer to this.

On my local Laravel 5.1 installation, I have a login that works perfectly fine. When I deploy to production, I can not login at all. I have all the appropriate headers and _token fields.

It appears that every time I refresh the page, a new session is created.

I've read a couple places that it could have something to do with the my computer's clock not matching the server (which it doesn't match, but I am on a network group so can't adjust it).

The other possibility is that the domain is only setup to work locally as we are in the process of transferring the domain.

Any other ideas as to what could be happening? I am running locally on WAMPserver and in production on Centos.

Thanks
