This issue may arise due to multiple reasons, as you mentioned.
Slow Internet connection
Computer Security software is preventing the MathWorks Installer from connecting to the MathWorks servers. This is known as a connection issue due one or more of the following:
  • Antivirus Software
  • Proxy
  • Firewall
Antivirus Software
To temporarily disable your Antivirus on a Mac:
  1. Locate the Antivirus icon found on your Mac menu bar.
  2. Click Shut down or disable temporarily until installation and activation have completed.
The MATLAB installer, activation client and update installer will try to automatically inherit your computer's proxy settings on Windows. If this process fails, you may need to manually enter your settings using the "connection settings" button on the first screen of the installer or activation client. The update installer will not allow you to enter your proxy credentials as it automatically inherits your computer's proxy settings. On Mac and Linux, you will always need to enter these settings manually.
To disable your Proxy in Chrome:
  1. Open the Customize and Control Google Chrome menu by clicking on the three-dots icon at the top right of Google Chrome, select Settings on the right, find Advancedand finally select o*pen proxy settings.*
  2. Select the LAN Settings button.
  3. Deselect the checkbox for Use a proxy server for your LAN.
To disable your Proxy in Safari:
  1. Go to Menu and click on Preferencesfrom the drop-down menu.
  2. Select the Advanced tab and then click on the Change Settings button.
  3. Deselect the checkbox for Use a proxy server for your LAN.
To disable your Proxy in Firefox:
  1. Click the Tools button and select Options.
  2. Go to the Advanced panel and select the Network tab.
  3. Click on Settings in the ConnectionSection and select No Proxy.
You will need to contact your IT Help Desk to troubleshoot this issue if you don't know your proxy settings or the error persists after entering your proxy settings.
You will need to contact your IT Help Desk if your organization is running a network firewall to configure it to bypass blocked connections to the MathWorks servers.
The MathWorks installer needs to contact MathWorks servers on the following ports and addresses:
  • TCP ports 80 and 443
Your firewall needs to bypass blocked connections for both addresses over both ports. These servers do not use a Static IP Address and will resolve to a Dynamic IP Address. This means that users will not be able to white-list MathWorks servers via IP Address and will have to use the domain name.
To resolve the issue for now, please obtain a license file and activate manually without the internet to complete the activation process.
To do so, follow the instructions in this article:
How do I activate MATLAB without an internet connection?
If you are unable to resolve the issue by the steps above, please contact Installation and Licensing Support:
If the MathWorks installer is still unable to connect after troubleshooting your proxy and firewall, submit a service request using the link below. Please include the troubleshooting steps you took to resolve the connection issue, and include your installation log file. See this related article if you need assistance locating your log file:
