Hi,

I see the same error with R2023B and there is no proxy in use. I have direct connection. How to resolve this error with Simulink?

Thanks

Hello Aadel,

I understand that you are getting the mentioned error while running a simulation. The error indicates that MATLAB is having trouble establishing a secure connection due to an issue with a certificate authority (CA).

Please recheck your internet connection and update MATLAB to ensure that you have the latest version of MATLAB. Also, please verify the system date and time.

If the issue still persists, try checking MATLAB web preferences using the following steps:

• Go to the Home tab in MATLAB.
• Click on "Preferences."
• Select "Web" from the side menu.
• Verify or adjust your proxy settings here. If you're unsure about the correct settings, you may need to contact your network administrator.

You can also disable SSL verification. I hope this helps!
