I've just installed Matlab R2019b. However, there seems to be a connector error.
Similar warning appears whenever I try to run a script or open a ".mlx" file (can't open .mlx). I've installed JAVA, deactivated my Firewall and tried to use the administrator mode to run matlab.exe, but they didn't work.
Any idea on how to fix it? ?

Hi @Elise,
I have found a similar question that addresses the same issue.
Refer to this link for the complete solution:
https://in.mathworks.com/matlabcentral/answers/446598-did-not-start-the-server-desired-port-was-31415
The process adds an exception in the Windows Firewall to allow traffic through a specified TCP port, enabling specific network communications by permitting connections that would otherwise be blocked.
I hope this was helpful.
