Hello Ioannis,

Are you using the Cobra Toolbox in MATLAB?

I was experiencing a similar issue recently and it turned out that my Gurobi license had expired.

Do you have a currently active gurobi license stored in a directory accessible to MATLAB?
What happens when you run changeCobraSolver('gurobi','LP',1,1)?

Yes, that was the problem. My license had expired so I renew it. I got a little bit late till understand that but ok. Thank you.
