Dear forum members,
I recently installed HCI 6.11.3 on physical server, I keeped the default ip address and subnet in the management interface (physical and its name is eth2),
and i accessed the server GUI via 10.250.0.7 and i created 2 more subinterfaces in the eth2 (eth2.2320,eth2.2330), then i changed the overlay interface from eth0 (down interface) to the subinterface eth2.2320, the management IP has stopped responding, When i tried modifying the network settings from the server console it does not save this changes, i tried to restart the server and when i tried to access the 'network settings' in the console i am getting this error

what can i do please ?

it sounds like the issue occurred after changing the Overlay Network from the default eth0 to a VLAN sub-interface (eth2.2320). This is a common cause of management connectivity problems if the network design or interface assignment isn't complete.
