Environment

VMware vCenter Server 
VMware vSphere ESXi 

Cause

Switch configuration and Firewall settings. 

Resolution

Involve your internal networking team to check your Switches and L2 bridge domain configuration as well as the firewalls to ensure that it's not affecting NFS traffic on different switches.
