Docker containers work on port 80 only

I tried this on multiple machines (Win10 and server 2016), same result using this tutorial: https://docs.docker.com/docker-for-windows/#set-up-tab-completion-in-powershell

This works

docker run -d -p 80:80 --name webserver nginx

Any other port, fails with

docker run -d -p 8099:8099 --name webserver nginx --> ERR_EMPTY_RESPONSE

Looks like Docker/nginx is listening failing on this port, but failing. Telneting to this port shows that the request goes through, but disconnects right away. This is different from when a port is not being listened to on at all.
