Linux blocking access to docker port

I would deploy my SF4 app on VPS. It's running other Symfony app, but in normal way without Docker. I prepared docker build, php-mysql-nginx-kibana, it is working on my MacOS HS. I pushed it to VPS and I can't access nginx.

root@bike:~/docker-symfony# netstat -tulpn

On port 800 is app which I want share, so I access IP:800 and I am getting

ERR_CONNECTION_REFUSED

What I am doing wrong? VPS is Ubuntu 16.04.
