This error occurs because the host name is not being resolved properly. To work around this issue you can either set your hostname to 'localhost'
dctconfig('hostname','localhost');
Or execute the following line of code at the MATLAB command prompt, making sure to copy the string output of the Java
This should be the short names but might not be (some PC's think their name is different than the DNS name). For example:
java.net.InetAddress.getLocalHost.getHostName
>> java.net.InetAddress.getLocalHost.getHostName
ans =
johns-computer
dctconfig('hostname','johns-computer');
