Hey @Jmorrison_GY,
Sorry for the delay.
I was checking the logs and I see there are a few warnings from the driver your NIC is using: bnxtnet. Maybe there is an issue with the driver version you are using. Could you please connect to Host 1 and Host 5 and run:
esxcfg-nics -l
esxcli software vib list
Copy both outputs here.
