If the server is in a private network behind a NAT, ensure these **ports are forwarded** to the server.

+Shaarli makes outbound HTTP/HTTPS connections to websites you bookmark to fetch page information (title, thumbnails), the server must then have access to the Internet as well, and a working DNS resolver.
