Hi @mglaize 

Did you try stopping all servers and starting all servers?
If you are unable to start node manager and need to analyze you will need to refer to logs in detail. but if you try a reconfiguration on middle ware server it should most likely bring it online.

Thanks & Regards

Hi,

Can you please tell me the few points:

1. is this the fresh installation? 
2. If this is not fresh installation, what changes you made due to that you faces this issue?
3. If this is fresh installation, if possible share the Prerequisites and installation logs?

Thanks & Regards,

Pankaj
