Try checking your Internet Options in the Control Panel and setting an exception:

Internet Options --> Connections --> LAN-Settings --> Advanced -> Exceptions (add localhost)

Otherwise, if you prefer not to modify your Windows settings, you could configure MATLAB Web Preferences:

In MATLAB: Preferences --> Check Use a proxy server to connect to the Internet and fill Proxy host and Proxy port. Then if necessary check Use a proxy with identification and fill Proxy username and Proxy password.

I can't even sign up for simulink or for matlab. When I try to open simulink or press the sign up button, all I get is a white window. I can't type anything in the window.

Has somebody a solve for this problem?

What worked for me, Matlab 2019A, Ubuntu 21.04:

• Open in browser https://localhost::31515
• Allow connection. Open developer mode->security->certificate->details. Or just show certificate
• Save it as localhost.pem
• Rename localhost.pem file to localhost.crt file

$ mv localhost.pem localhost.crt

• Make folder (under sudo) /usr/local/share/ca-certificates/matlab
• Give it correct access

$ sudo chmod 644 matlab

• Copy crt file into matlab folder
• Give it correct access

$ sudo chmod 755 localhost.crt

• Update certificates. Example output is below

$ sudo update-ca-certificates
Updating certificates in /etc/ssl/certs...
    1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
    Adding debian:localhost.pem
done.
done.

• After that https://localhost::31515 should open in the browser. Or fail with `ERROR_SELF_SIGNED_CERT`, that's okay
• And Simulink should work as well. Don't forgot to restart it before checking
