This occurs when an active VPN connection interferes with IP address lookup of 'localhost' or the machine's own hostname.
To resolve this, you may either:
A. Disable VPN and launch again.
B. Edit the OS's
hosts file to include this line as the first setting:
127.0.0.1 localhost myHostName myHostName.company.com
...where
myHostName and
myHostName.company.com are replaced which correct values for your system.
On Linux and OS X, the
hosts file is in found in directory
/etc.
On Windows, the
hosts file is found in directory
C:\Windows\System32\drivers\etc.
