i downloaded HDF 3.0 for virtualbox
i imported the machine and started it everything seems to be OK
when i try to access the tutorials url "http://127.0.0.1:18080/" or "http://127.0.0.1:18744/"...
but it gives error.
it seems that is refused on 127.0.0.1. I can't access to 18080 or 18744.
but i can connect to "http://127.0.0.1:18888"
i hope somebody help me.
does SSH work? The HDF Sandbox had a quirk in the past that if the VM was ever shutdown, then it would need to be restarted using the scripts within the Docker host. If this is the case, try suspending/pausing instead of shutting the machine down. See the post here for a detailed walk through in case it resolves your issue:
From your screenshots, its looks like you can get to the docker port on 12122. If you login to that one via SSH, you can follow the steps in the link I shared with you above to start the HDF sandbox VM, and try that.
