License Manager Error -1, Licensing error: -1,359. System Error: 2

I was directed here from my own license failure and cannot find any corresponding information myself.

My academic installation was running fine for several weeks, but now I receive this error when starting matlab:

MATLAB is selecting SOFTWARE OPENGL rendering.

License checkout failed.

Licensing error: -1,359. System Error: 2

I have tried deactivating and reactivating matlab to regenerate the license file to no avail. I had no problem with initial activation using the online system. I believe the error might have been caused by automating the bash command "killall MATLAB" to terminate stalled processes during pipeline processing that I've been performing, but I'm not sure.

This is probably caused by running

matlab -c <license>

without specifying a license file, for example as

matlab -c;
