Recurring License Manager Error -9 in HPC Environment Due to HostID Changes - Licensing error: -9,57.

Hello MathWorks Community,

We are running MATLAB R2024b on an HPC cluster and have encountered the following error multiple times this year:

License Manager Error -9: Host ID mismatch

Host ID '0000037bfe80' in the license file does not match your computer's host ID: "00000457fe80 00000382fe80 1423f2b44861 1423f2b44860 1423f2573891 c4cbe1a6833d 1423f2573890 c4cbe1a6833c".

Our license file currently includes these HostIDs:

0000037bfe80

00000439fe80

1423f2573890

1423f2573891

1423f2b44860

1423f2b44861

c4cbe1a6833c

c4cbe1a6833d

Current HostIDs detected by MATLAB:

Hi Maria,

Have you changed the hardware/adapters (therefore MAC addresses) in the past? If so, I assume the hostID 0000037bfe80 was one of old ones and was used to activate MATLAB. So now if you try to activate for the hostID c4cbe1a6833c for example, you might get the same license file.

Hint: the -activate flag won't trigger the activation client MATLAB, and if you want to run the activation client, you will need a GUI. You can also activate MATLAB manually.

I suggest picking out the adapter that you plan to keep for a long time, then please reach out to our support team and we should be able to help further:

Installation and Licensing Support can be reached at [phone]. Dial option 3, then 1 at the menu

Please consider giving us a call, or an email for licensing issues as we have access to more licensing information on our end ^^
