Matlab Add-On Explorer and Updates not working behind Proxy Server and Firewall

Hi. We have a problem with our Matlab users. The Matlab Add-On Explorer is able to browse Add-Ons, but whenever the users try to install a selected Add-On, the connection fails. We have looked at the logs from the Proxy Server as well as the Firewall, and cannot see why the connection fails. A connection test shows Success. Please see screenshots below. Is there another web server or domain other than mathworks.com, or a different port other than 80 and 443 that Matlab is trying to connect to? Any suggestions would be appreciated.

We're having the same issue with updates. Updates are being notified but can not be downloaded.

I can't find an offline updater either.

Please try to run the following in the MATLAB Command Window:

>> opengl software 

And then try opening the Add on explorer again. It worked for me.

If that works, you can save the preference so that MATLAB always opens with Software OpenGL by running:

>> opengl('save','software')
