local & localhost:8888 works; but 127.0.0.1:8888 doesn't work

Hi,

When I attempt to direct to “tutorials”, local & localhost:8888 works; but 127.0.0.1:8888 does.
port 8888 is set in VM.

in addition, in the file HOSTS
127.0.0.1 localhost sandbox.hortonworks.com
doesn’t work too.

any solution to this problem?

Thanks!
