Veeam B&R 9 failed to connected to Hyper-v cluster however, it was working two days ago properly. When i choose backup Infrastructure >>>>>managed servers...Microsoft hyper>>>>hyper-v clusters, it shows the cluster IP address, but can't expand nodes under it. I got the error ' failed to create hyper-v clusterWmiUtilis: server does not exist or access denied, check firewall settings'
and if I perform right click on cluster IP address and click rescan it generates "Host discovery failed"
I did the following attempt but with no success :
1-Disable firewall and antivirus on Cluster nodes.
2-confirmed that the veeam account used in configuration is local admin in all nodes.
3-Tried to reconfigure again with Domain admin account.
Could any one help me, please?
