accessing ambari on HDP 2.6.4 sandbox in docker on AWS Linux

[#1]

After running the HDP sandbox script, all looks well: The output (see below) says Ambari is up, and the Hortonworks HDP container is started, but Ambari commands don't work. I can't access Ambari on port 8080. Any help will be greatly appreciated.

Ambari is up and awaiting connections on port 8080

Problem solved, well understood anyway. I tried it at the office and voila, there's the Ambari login. I'll fiddle with my home firewall.
