Hi
1. Please check if you can telnet to VR IP on port 5480. Try a different browser/system to connect to VR VAMI
2. Login to VR VM and check the status of VAMI service on VR appliance:
systemctl status vami-lighttp.service
systemctl status vami-sfcb.service
If not running, you can start them by running 'systemctl start' command for both of these services. Stop and and start services is also worth a try if the services are already running
3. Run these commands to enable the service and reboot the VR appliance:
systemctl enable vami-lighttp.service
systemctl enable vami-sfcb.service
Hope that helps
