I got the error message "Unable to communicate with required MathWorks services (error 5001)

I installed MATLAB 2023b, but I could not started it with my Kaspersky VPN active, but if I turn it off, I can connect very well.

Anyone knows how to tunneling the MATLAB services throught my Kaspersky VPN?

Hi Wilbert,

I understand that you are looking to configure MATLAB so that it operates seamlessly while Kaspersky VPN is active.

Experiencing difficulties with MATLAB while Kaspersky VPN is enabled may be due to the VPN blocking essential communication channels that MATLAB relies on. Here is how one can address and potentially resolve the issue:

• Review Kaspersky VPN Settings for any rules or firewall configurations that might be preventing MATLAB from operating correctly. It might be necessary to tweak these settings to facilitate MATLAB's connectivity.
• Consider adding MATLAB to the list of exceptions in VPN's firewall or security settings. This action instructs the VPN to permit MATLAB's network traffic.
• Configure Port Forwarding as MATLAB may need specific ports to be accessible to initiate and maintain its services. Consult MATLAB's support resources to identify the required ports and then set up VPN to allow traffic on those ports. Refer to the link- https://in.mathworks.com/matlabcentral/answers/96756-what-ports-does-the-network-license-manager-use-and-how-can-i-set-those-ports
• Utilize Split Tunnelling feature of VPN if available. This allows to direct only certain traffic through the VPN while letting MATLAB use a direct, unimpeded connection.
• Seek Support Assistance about how to adjust VPN settings, Kaspersky's customer support can provide guidance tailored to ensuring compatibility with applications like MATLAB.
• If using a network license for MATLAB, VPN might be disrupting the connection to the licensing server. Make sure that the VPN configuration allows network communication with the licensing server's address and port.
• Ensure that both Kaspersky VPN and MATLAB are running the most current versions, as updates often fix known issues and improve overall compatibility.

Exact steps may vary depending on the version of VPN software and its specific features. If configuring Kaspersky VPN to work with MATLAB proves unfeasible, one may need to explore alternative VPN solutions that offer better compatibility with MATLAB or provide the necessary configuration flexibility.
