I disabled SSL on my DNS settings and it works now. Interesting.
How can I use GameAP via HTTPS?
Should I update Client Certificate somehow?
I use CloudFlare services.
Edit:
Authenticated Origin Pulls
TLS client certificate presented for authentication on origin pull.
You should TURN OFF this, I think this caused my problem.

Unfortnately GameAP Daemon needs to be restarted sometimes.
sudo service gameap-daemon restart
