[ovirt-users] Error during deployment of ovirt-engine

Hello all I'm trying to deploy an oVirt Engine through the cockpit interface. Unfortunately the deployment fails with the following error: [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set admin username] [ INFO ] ok: [localhost -> 192.168.222.95] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for ovirt-engine service to start] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Open a port on firewalld] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Expose engine VM webui over a local port via ssh port forwarding] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Evaluate temporary bootstrap engine VM URL] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Display the temporary bootstrap engine VM URL] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Detect VLAN ID] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Set Engine public key as authorized key without validating the TLS/SSL certificates] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Obtain SSO token using username/password credentials] [ ERROR ] ovirtsdk4.AuthError: Error during SSO authentication access_denied : Cannot authenticate user Invalid user credentials.

I tried both complex and simple passwords for root/admin but none worked so far.
