Looks like a problem for tech support.

[Walter Roberson]

This could be due to internal firewalls blocking MATLAB from creating connections to the host itself.

There is a generic knowledgebase article about the "31515 error here, which points to firewall topics as mentioned in the comments. And yes, if you and your IT cannot solve this, please contact MathWorks support.
