If you are getting an IP address of 127.0.1.1 out then that indicates that your primary ethernet is set to IP address 127.0.1.1 and that you must be using a different IP address for your actual communication.

All IP addresses that start with 127 are reserved as being internal loop-back addresses that are never accessible outside the host. See RFC1700 paragraph g

It is possible that earlier you had to lock your hostid to an ethernet MAC address and you picked one that you do not actually use; see http://www.mathworks.com/matlabcentral/answers/102676-how-can-i-activate-matlab-on-a-linux-machine-that-does-not-have-an-eth0-device

To find more realistic IP addresses for your system see http://stackoverflow.com/questions/13322485/how-to-i-get-the-primary-ip-address-of-the-local-machine-on-linux-and-os-x

However with the 127.0.1.1 I suspect that MATLAB might have gotten fooled and accidentally created the TCP socket against a loopback address :(

If you were not aware that you were using 127.0.1.1 for your IP address on an interface, you should probably change it to 127.0.0.1 . That might involve changing your hosts file or equivalent.
