Hey,
I'm having an issue at the moment adding ESXI hosts Via their Natted IP address to vCenter VCSA 6.5.
Previously I have successfully used this KB successfully Using NAT between the vCenter Server system and ESXi/ESX hosts (1010652) | VMware KB for all previous version of vCenter.
The Server IP address in the vpxa.cfg file is correct and port 902 is open and telnet works

I have increased the config.vpxd.heartbeat.notRespondingTimeout via this KB

Here is a tail of the vxpa agent log
