Unable to follow "Sandbox" links from Mesos UI

[HelloGrayson]

After running the container example from the README and then going to the Mesos UI, this error is received when clicking on the "Sandbox" link for a running task:

Failed to connect to slave '20140927-181543-486543788-5050-1-0' on '7af7848f5538:5051'.
Potential reasons:
The slave's hostname, '7af7848f5538', is not accessible from your network
The slave's port, '5051', is not accessible from your network
The slave timed out or went offline

Looks like you might need to add MESOS_HOSTNAME=<some_resolvable_hostname> .......

[HelloGrayson]

Aha! Looks like you're right. Fix coming up now!

[HelloGrayson]

Hi Fellows.. I´ve got the same error. If the fix is to set MESOS_HOSTNAME.. somebody can tell us where and how to do that;

All best,

doesn't work by adding MESOS_HOSTNAME to /etc/hosts

[HelloGrayson]

localdocker will have to point to the right IP.

[rushabh268]

You need to add the hostname to the /etc/hosts of the VM which is running the Mesos browser. In my case, it was my local linux and not the master so there was no benefit modifying the master's /etc/hosts

[pangbingqiang]

i have fixed it, do not use IE explorer and then in /etc/hosts must set the hostname of cluster for master and slaves

After adding mesos master/slave hostname and IP addresses in the /etc/hosts file on both systems. Also restart mesos, zookeeper, and marthon services and the problem still exists.
