MathWorks Licensing Error 96 when running a Docker image of MATLAB in a GitLab Runner

I'm using the MATLAB Docker Image in a GitLab Runner and I get an error message when trying to run MATLAB in the Docker image. Specifically, I see the Runner using the Docker image try to run my MATLAB script:

$ matlab -batch "myScript.m"
License checkout failed.

Check that the GitLab Runner isn't blocking the port to the license server. To do this, you can use nmap or similar utilities.
