Could anybody help? The sandbox was loaded last week is version 2.6.5 on ubuntu 18.04 LTS. Login do the server itselfs is working, but than the connection from the server to the docker image is not working.

Error message is:

On Ubuntu 18.10 and version 2.6.5 of HDP I have the same problem. The docker 'sandbox-proxy' is listening on 8080:

tcp6 0 0 :::8080 :::* LISTEN 23673/docker-proxy aus (0.00/0/0)

How did you solve your problem, as I am experiencing the same problem while using HDP Sandbox with docker on a ubuntu machine 16.04


Same problem here.

New Contributor

Have the same issue. Is anyone still working on this?

New Contributor

I resolved this by shutting down the firewall on the HDP Sandbox container:

sudo systemctl stop firewalld

sudo systemctl disable firewalld
