Hi Xinlai,

The issue is likely caused by an internal Certificate Authority (CA) used in your network. MATLAB installers for newer versions handle certificates differently, so upgrading to a newer release may resolve the problem. If you must install an older version, you can proceed with below troubleshooting steps.

Some corporate networks use self-signed certificates through proxies, gateways, or firewalls. While these certificates work internally, they are not trusted by Oracle Java, which the MATLAB installer relies on. When the installer connects to external MathWorks services, Java rejects the certificate, causing the connection failure.

Possible Solutions:

• Log into your MathWorks account first: Sign in at https://www.mathworks.com and then run the installer again.
• Whitelist MathWorks domains: Ask your network administrator to allow "services.mathworks.com" and "login.mathworks.com". This prevents the proxy from attaching the untrusted certificate.
• Use a trusted certificate authority: Replace the self-signed certificate with one from a trusted CA (e.g., DigiCert, VeriSign, Thawte).
• Bypass the proxy/network filtering: Install MATLAB using a different network such as a guest network, mobile hotspot, or home network.
