"The application could not connect to MathWorks" on Matlab start

I'm getting this error message when starting Matlab. A pop-up windows comes up and after pressing "OK" the application works correctly? Anybody knows why am I getting this error message? Any help is appreciated. Tnx

Did you try Googling your error? The first result should be your answer.

@Alession: When starting the Matlab-Installer or when an already installed Matlab is started.

[Alessio Capuano]

@jan I get the error once I'm starting the session. The matlab-installation process worked correctly and I had no problems with it.

I have the same issue as Alessio, and the answer below was no help. I don't seem to have a SupportPackageInstaller, and the install accepeted the proxy and went fine. When I enter 'matlab' at the prompt, I am challenged to log in to my account and it can't do it. There is no advanced button to enter proxy information.

I hesitate to post the first 2 Google matchs, but the solve the problem most likely:

• https://www.mathworks.com/matlabcentral/answers/92634-why-do-i-get-a-connection-error-when-installing-or-activating-matlab-or-another-mathworks-product

Thanks a lot @jan. It is exactly the case of the first link.

Hello,

I tried with a lot of answers including turning off the antivirus and firewall but it did not work. I went this morning to the lab in the university and I tried again to install it and it finally worked !!!! I think because the VPN because at home I have viber 2.5G/s but it was too slow last night. In the lab, the internet connection is too fast and I also used VPN of the university.

Note: I connected as student in the university because I am a PhD student but my problem is that the screen was frozen when I finished writing my password to access my account to activate MATLAB.

Some suggestions:

• Try to connect via VPN.
• Try to connect to fast internet connection.

I hope this helps someone.

Keep trying, do not give up.
