Error HostID mismatch (licensed to 5540d185, hostid is 56c2be70)

Hi everybody,

I implemented my MILP using C++ and Gurobi on an UBUNTU enivrement.
In order to do some experiments I connect to an other server machine with my personnal account (In wich I have Gurobi and the license) but when executing the program I have this error message:

Error code = 10009
HostID mismatch (licensed to 5540d185, hostid is 56c2be70)

I understand that it is a license problem but I d'ont know how to fix it.

In fact when I connect to the remote machine I am using my local account in which I have already all needed Gurobi, licence, g++ and everything works but the licence of Gurobi.
Should I have another license for the server machine? and when should i put it or how to configurate my program to take into account this licence?

Thank you a lot for your response.

Best regards.

Nadia

For a free academic license, you need a separate key for each combination of user and machine. Go to the Gurobi website and get an additional key for this new machine.

Thank you for your answer. I generate a new key and it works now.
