Asking this question in case anyone else has faced the same problem / has found a solution.
Release: R2015b 64 bit, Windows.
When clicking on "Get Add-Ons", this error message pops up on the command window:
Error using connector.ensureServiceOn
Error starting MATLAB Connector. Please check that port 31515 is available.
com.mathworks.jmi.MatlabException: Error starting MATLAB Connector. Please check that port 31515 is available.

What I've tried:
- Allowed R2015b.exe in the Firewall for inbound and outbound connections.
- Allowed TCP port 31515 in the Firewall for inbound and outbound connections.
Still no luck.

Hi,
The issue is related to the network configuration. One possible workaround is forcing JVM to use IPv4 over IPv6 by setting the java.net.preferIPv4Stack config. The following discussion page provides some relevant discussion:
To work around this issue create a new System Variable named JAVA_TOOL_OPTION, with the value -Djava.net.preferIPv4Stack=true

I solved the problem by deleting the MATLAB_JAVA path in my system variables.

Don't go for rubbish like "it's because of JAVA". This happens when MATLAB is blocked by some firewall that is blocking MATLAB from connecting to Internet. MATLAB uses Internet during Stimulation. Just exclude it from firewall and there you go. There will be no error.

This answer really helps me. After I exclude MATLAB from the firewall in the computer, the error never come up.
