Host cannot communicate with one or more other nodes in the vSAN enabled cluster

For 2node vsan cluster in nested lab I did follow:

lhost1 (mgmt ip = (vmk0)10.10.50.10 , vmk1 vsan ip = 50.50.50.50)
lhost2 (mgmtip = (vmk0)10.10.50.11 , vmk1 vsan ip = 50.50.50.51)

also deploy witness ova (mgmt ip = 10.10.50.13) , vmk vsan ip = 50.50.50.53

now from each host can ping both range
also define witness traffic on mgmt on lhost1 and lhost2

esxcli vsan network ip add -i vmk0 -T witness

but now due create vsan 2node cluster after finish wizard (task successfully complete)  on both host (lhost1,lhost2) show this : Host cannot communicate with one or more other nodes in the vSAN enabled cluster
also performance service is such as attach pic.

How can solve the issue also reboot boot esxi host
