Sometimes I've seen issues like this and the resolution is either:

Disconnect / Re-connect the host in vCentre
Restart vCentre server

Troy,

Do you mean vcenter vcsa? or just the ESXI host in question?

I do have the same exact check on other ESXI hosts and they are fine.

Even on this host I have the same check just with different tests CPU Memory VMFS etc. they all work only the Network check does not.

Thanks

Tom

Ps is the MSW still working? will it work with 6.7 of ESXI and vCenter?

I've seen cases where you need to restart the entire vcsa however normally all checks for one host do not work.

Are you seeing any errors in the vCenter or ESXi host when the check fails?

MSW should still function fine with 6.7 of ESXI and vCenter?

I am running vcenter in HA mode so I have 3 VCSA appliances

Primary
Passive
Witness

Do you know which log to review on the esxi host

Currently I removed that check for now.

They all were recently upgraded to 6.7

Need to wait for next maint window if I want to restart them.

In an HA setup I would have to shutdown all three not sure why the VCSA would effect this check.

Thanks

Tom

On the ESXi host, using the vSphere web interface navigate to Monitor > Tasks and Events . Look here to see if any errors are logged.

Other than that I'm not entirely sure, if it's just this one ESXi host and the problem is not resolved after restarting and/or disconnecting/reconnecting the host then there must be something configuration wise on the ESXi/vCenter that needs diagnosing. Sometimes it can be quicker to re-provision the ESXi server from scratch as a simple configuration mistake might take longer to track down then just a fresh install.
