mano OSM vIM creation issue

[Mehdi]

The installation is performed on dedicated server on proxmox .
VM1 (openstack train -controller node ): IP -> 172.16.1.100
VM2 (MANO v10): IP 172.16.1.109
Ping controller- MANO: ok
Ping MANO - controller :ok
After installation on openstack client on MANO VM2 and run. admin-openrc , MANO can discover image list , flavor list… existiong in openstack . Output of : _AUTH_URL=http://172.16.1.100:5000/v3 -OK
In openstack i have a provider network , type : Flat to allow instances connect to the internet.

as whenever i log-in to MANO web interface to create vim ( or by CLI ), Or " osm vim-create --name openstack-site --user admin --password userpwd
--auth_url http://172.16.1.100:5000/v3 --tenant admin --account_type openstack"

--> the operational state equals to "error".

--> LOG Keystone : cat /var/log/keystone/keystone. log show bellow:

2023-11-09 16:04:46.712 2322 WARNING keystone.server.flask.application [req-295ae54a-bf73-499b-be7b-8d653d32f779 - - - - -] Authorization failed. The request you have made requires authentication. from 172.16.1.109: Unauthorized: The request you have made requires authentication.

According to MANO site , it's recomanded to create on openstack an isolated provider:physical_network, but this opetion its not working in my case .

Any kind of help would be much appreciated, as I've being struggling for a week now. Thanks in advance!
