cachet: CSRF token validation failed

I am totally sure it has to do something with my environment but I could need a little help. I alway had Cachet good working on Redhat OpenShift, as they are moving to a new platform I decided to move away to my own FreeBSD server.

As for my enviroment I have downloaded the source with Git and followed the whole documentation https://docs.cachethq.io/docs/installing-cachet. I use FreeBSD 10, PHP56, NGINX, composer and PDO MySQL extension.

As for this issue I already cleared cache, did a new app:install, config:cache, got my app:key nicely filled in my .env-file, correctly set permissions for my WWW-user:777 (temp) and such sort of things.

I have no caching apps tho. Any idea what this could be? When I browse to https://status.domain.com/setup I see the config page and as soon as I fill in my stuff I get: “CSRF TOKEN VALIDATION FAILED”.
