Matlab license error

[sayaz...@gmail.com]

Dear Powder team,

I was willing to run an experiment on mMIMO MEB rooftop setup. While trying to run Matlab I am getting some license error as below:

Exp. name = otfs

Profile = renewlab

I am using pc18-fort (d840)

sayazm@pc1:/usr/local/MATLAB/R2021a/bin$ ./matlab
MATLAB is selecting SOFTWARE OPENGL rendering.
License checkout failed.
License Manager Error -15
Unable to connect to the license server.
Check that the network license manager has been started, and that the client machine can communicate
with the license server.

Troubleshoot this issue by visiting:
https://www.mathworks.com/support/lme/R2021a/15

Diagnostic Information:
Feature: MATLAB
License path: /users/sayazm/.matlab/R2021a_licenses:/usr/local/MATLAB/R2021a/licenses/license.dat:/usr/local/MATLA
B/R2021a/licenses/network.lic
Licensing error: -15,570. System Error: 115

Can you please point me on how to fix this ?

Thank you,

Ayaz

Sorry about that -- the server had not been updated to the current
renewal. Please try again and let us know if the error still
occurs.

Thanks,
Gary.

Apologies for the regression. We rearranged the shared VM pool recently
and the server process didn't restart up properly. Please try again now
and let me know if the error still occurs.
