Doc: explain how to release the license #6

Closed MaximeWeyl closed 1 year ago

When building my docker image with matlab-proxy, I need to rebuild and rerun the image several times. I use my license through the online license server. I often am unable to rerun the newly built image because the license was not released on the previous one I juste stopped (error License Manager Error -4)

I tried to use "Stop Matlab session", and "Sign out" buttons from the floating popup but the issue is still happening, and I have to wait for a long timeout for the license to be released and available again.

Hi @MaximeWeyl ,

Thank you for trying out the matlab-proxy package. Can you try typing out 'exit' in MATLAB and see if the licensing issue still persists ?

As the "Stop MATLAB Session" and the "Sign Out" buttons should also serve the same purpose, once after you know that you are able to license MATLAB, can you try again by clicking the "Sign Out" button and let us know if you are still seeing the "License Manager Error -4" error ?

Hi, I tried again like this :

On the first container host :

Start matlab with my email and password
Do a few operations in matlab to see its working
type exit (the matalb console becomes unresponsive)
use the stop matlab button (It goes back to the start screen with the buttons)
use the sign out button (it shows the login screen again)
stop my container

Then I start a new container on another host, with the same docker image :

I type my email and password and ask for a matlab start
Matlab proxy seems able to validate my email and password but shows error -4
