During the first step of setup matlab, it shows "unable to connect to host"

what's the problem?

I am sure I have already connected to internet and I closed all anti-virus softwares and windows firewall.

Do you have a proxy enabled? Do you have a VPN enabled?

A couple of months ago there were hints that login.mathworks.com might be blocked by China.

I am a college student and I am using school internet while I install matlab. My university has bought matlab and I have to link to school internet while I am installing it.

Hi @hong xu,

The error you are encountering typically happens because MATLAB's installer or activation client can’t connect to MathWorks servers. It may be due to:

• Firewall restrictions
• Proxy settings misconfiguration
• Network-level blocks
• Missing or improperly set environment variables

Even if your system firewall is off, your organization’s network proxy or VPN settings might be causing this.

For full troubleshooting steps, refer to the official MathWorks guide: https://www.mathworks.com/matlabcentral/answers/482075-why-do-i-get-the-error-unable-to-connect-to-host-connection-timed-out-connect-when-installing-or?s_tid=srchtitle

I hope this helps!
