I'm having the same issue, although my internet was connected the entire time. I've tried on three computers: two on a company network that requires proxy and one on my home network/no proxy in case that has something to do with it. I've tried rebooting / running matlab as administrator / downloading the package installer separately. Nothing has worked. Two of the computers are Win10 and one is Win 7. Matlab version is R2015b and the add-on I'm trying is MinGW 4.9.2. I installed this exact combination (R2015b / MinGW) on a different Win10 computer ~ 1 month ago without issue. Help! Thanks!

Java.opts solution did not work for me, but this did:
"""
Just download and install to the "C:\TDM-GCC-64" folder
3) In matlab call the
setenv('MW_MINGW64_LOC','C:\TDM-GCC-64')
4) In matlab call the
mex -setup
"""
Working solution was provided by Hasan Sari in the comments section of the MATLAB Add-on page for the MinGW-w64 C/C++ Compiler (Home-->Add-Ons-->Search"mingw"-->Select"MATLAB Support for MinGW-w64 C/C++ Compiler ")

I'm having the same issue during arduino package installation, although my internet was connected the entire time. I've tried many times. I've tried rebooting / running matlab as administrator / downloading the package installer separately. Nothing has worked. My computers is Win 7. Matlab version is R2015a. Please help me. Thanks!

That is a setenv() call that is shown. Copy the whole setenv call and paste it at the command line.

Putting this in as an answer instead of just a comment. Sorry for the duplication.
I've received two separate responses from Mathworks:
1 - There is an outage for a number of support packages and they're working on a resolution
2- for MinGW Ad-On for 4.9.2 specifically:
We have been running into issues with the MinGW Add-On for 4.9.2 that our developers are currently investigating.
One possible workaround to the MinGW installation issue is to manually download MinGW, and link MATLAB to the installation with an environment variable. To do so, download and install MinGW from the following location: https://sourceforge.net/projects/tdm-gcc/files/TDM-GCC%20Installer/Previous/1.1309.0/tdm64-gcc-4.9.2.exe/download
Be sure to uncheck "Check for updated files on the TDM-GCC server" when running the installer to insure version 4.9.2 is installed.
Once the installation has finished, create an environment variable named MW_MINGW64_LOC, and set the location to the folder where MinGW was installed. For example, if you chose to install at the default C:\TDM-GCC-64 location, you will set the variable to "C:\TDM-GCC-64".
To set the environment variable, open the Control Panel, and go through the options System > Advanced System Settings > Advanced tab > Environment Variables. Be sure to declare the MW_MINGW64_LOC variable in the System Variables section rather than the User Variables section. After setting the variable, hit OK and Apply on all menus to have the variable assigned.
When complete, you should be able to start MATLAB and run "mex -setup" and have the MinGW compiler recognized
These instructions worked for me.

FYI - don't include the quotes in "C:\TDM-GCC-64" when putting it into the environment variable.

About my problem, I sent a service request and the only thing that MathWorks could suggest me was that I should install R2017b. The full MathWors answer:
Thank you for contacting MathWorks Support. This error is currently being investigated by MathWorks. As this only affects MATLAB releases at or before R2017a, the only current workaround is to install MATLAB R2017b.
There is currently no ETA for when this will be resolved, but I will keep you informed as we receive updates.

Hello there. Finally, I have found a simple solution to this issue. Just you need to download the attached file, and then you must unzip the file. After that, you will find two folders; which are: bin and bugreport.
First step: open the bin folder, and copy the file that appears in it then paste it in your MATLAB folder in your C drive inside the bin folder.
The second step is that copy bugreport folder as is and paste it inside matlab folder.
Regards Hasan

The attached appears to be have been a copy of the .zip associated with https://www.mathworks.com/support/bugreports/1741173, the active part of which is a replacement java.opts . This is the same thing that the accepted answer by Bui Tuan leads to.
As Mathworks requires people to log in and go through a click-wrap agreement before using the attachment, I think it would not be acceptable to post the attachment without that layer of authorization, so I have deleted the attachment here.
