This error is indicates that ports on the loopback address in the error message are being blocked. There are many things that can cause this including, but not limited to:

• Installing from a shared drive. Move the installer to a local drive. 
• Antivirus/security software
• Operating System firewalls
• Misconfigured VPN
• Misconfigured hosts file
• Blocking said ports intentionally in another manner

If you would like to install MATLAB onto a shared network drive, run the installer from a local drive and set the destination to your network drive to avoid this error.
