Seafile cant download/upload files

Hello, i have CentOS 7 VPS + Seafile Server v7.0.4 + nginx.
Im forwarded 8000 and 8082 ports to my public ip address in pfsense.

So i cant upload and download files when im accessing http : // public_ip:8000 from WebUI/Client, but i can login to my account.

Here is my settings:
SERVICE_URL = http : //
FILE_SERVER_ROOT = http : //

When im in my local network i can up/down files

Can you help me?
