Hi ,

You can try with:
1. Set the host in maintenance
2. From Install dropdown , select 'reinstall' and then configure the necessary info +  whether you would like  to use the host as Host for the HostedEngine VM.

Once the reinstall (of Ovirt software)  is OK, the node will be activated automatically.

Best Regards,

Hello everybody,
since last update to 4.3.7 I get this error message:

Certificate of host host.name is invalid. The certificate doesn't contain valid subject alternative name, please enroll new certificate for the host.

Have you an idea of how I can fix that?

Regards
Jonathan
