Gurobi license problem on Yggdrasil

Hi,

I seem to be running into Gurobi license problems on Yggdrasil:

[remypa@login1 ~]$ module load Gurobi
[remypa@login1 ~]$ gurobi_cl --tokens
Failed to connect to token server 'master.baobab.hpc.unige.ch' (port 41954).
Problem retrieving token server status

Thanks

[This was initially posted in an existing thread, but it didn’t seem to get noticed. So I’m creating a new topic, as the problem is still there.]

Hi there,

Fixed:

[capello@login1 ~]$ date

[capello@login1 ~]$ module purge
[capello@login1 ~]$ module load Gurobi
[capello@login1 ~]$ gurobi_cl --tokens

Indeed (cf. Gurobi license expired on Yggdrasil - #5 by Patrick.Remy ).

Sorry for the delay and also for the annoyance, the problem was that during the 2021-02 Yggdrasil maintenance we changed some IP addresses (cf. Yggdrasil scheduled maintenance: 10-11 February 2021 - #4 by Yann.Sagon ) and forgot to update the Gurobi license server.

Thx, bye,
Luca
