Hello all,
Getting the below error message when trying to establish a Hyper-V cluster between 2 servers. I am using Windows Server 2016 Datacenter with Server Core. The Hyper-V role is installed. I use another physical server to graphically manage these 2 servers. I have 1 physical NIC being utilized by the operating system and a 2nd physical NIC configured as a vSwitch for virtual machines. I have more Hyper-V servers that I would like to establish a cluster with but I am limiting complexity right now, so I am only doing these 2 servers because they are on the same physical switch. On my switch there are ACL's that are configured. I created an ACL for UDP port 3343 and saved the configuration. On my 2 servers I disabled the Windows Firewall for domain, public, and private profiles. My network is using a /24 subnet mask on these 2 servers for all NIC's. There is a VLAN configured at the physical switch for all ports involved and within Hyper-V the same VLAN is configured for the vSwitches. Both servers appear to be listening on UDP 3343. I do not have Internet access from the network my Hyper-V servers reside on, so I cannot readily upload logs or error messages. They have to typed in by hand. I cannot easily apply patches at the moment.
Network interfaces server1.domain.tld – vEthernet (vSwitch) and
server2.domain.tld – vEthernet (vSwitch) are on the same cluster network, yet 10.x.x.x is not reachable from
10.x.x.x using UDP on port 3343.
Network interfaces server1.domain.tld – vEthernet (vSwitch) and server2.domain.tld – Host are on the same cluster network, yet 10.x.x.x is not reachable from10.x.x.x using UDP on port 3343.
Network interfaces server2.domain.tld – vEthernet (vSwitch) and server1.domain.tld – Host are on the same cluster network, yet 10.x.x.x is not reachable from10.x.x.x using UDP on port 3343.

I would appreciate any insights from anyone about this problem of mine.
