This issue occurs when one or more ESX servers registered in the vSphere Replication database has an IPv4 or IPv6 Link Local IP address. IPv4 Link Local address is defined in the range 169.254.0.0/16 and IPv6 Link Local address is assigned with the fe80::/10 prefix.
The issue can be avoided in vSphere Replication 8.7 by adding com.vmware.vr.disallowed Host tag in the ESXi host. To work around this issue:Try these common steps first. 1. Reconnect hosts in unresponsive state or remove them from vCenter inventory 2. Power OFF & Power ON VR appliance (Don't shutdown)3. Reboot vCenter 1. Take a snapshot of the VR appliance you intend to apply this fix on. 2. systemctl stop hbrsrv 3.
