We haven’t changed anything in the build process in months – it has worked until this past Friday morning.
Here is what we see:
License checkout failed. License Manager Error -96 MATLAB is unable to connect to the license server. … Licensing error: -96,7. System Error: 2

This answer will help you. You need to make sure that MATLAB machine can ping to license server and two ports of FlexNet and MLM are not blocked by firewall.

1. From MATLAB machine, open Command Prompt or Terminal,
ping SERVER_HOSTNAME
where SERVER_HOSTNAME is a hostname of the license server.
2. At the server, check the Firewall if incoming TCP ports are allowed. Two TCP ports are to be allowed. By default, lmgrd daemon uses 27000 and MLM daemon uses random port number, so you need to set a specfic port for MLM daemon by the settings written in this answer
