As per my understanding it could be due to credential issue, please check the credential.
I can log into the host with the same credentials so I don't believe the credentials are incorrect. Apparently VMware 6.5 presents them differently.
That error is showing that there is an issue with the CIM service running on the ESXi Host or the way that the CIM modules are being organized in ESXi 6.5 and what the SolarWinds Poller expects.
I have not read any posts where people are having issues polling 6.5 Hosts recently on Thwack so perhaps it is the sfcb (Small Form-factor CIM Broker) daemon running on the Host that is having an issue. You can restart the daemon using vSphere client or from the ESXi CLI. Either stop the CIM service with vSphere client and then start it up again or from the CLI stop the sfcbd-watchdog, wait for it to stop and then start it again - this works better than just issuing a restart command. If it takes a few minutes to stop the sfcbd-watchdog service then that is most likely the issue.
PS: It can take up to 30 minutes for the CIM service to become fully functional and for the SolarWinds polling to be able to poll the hardware status.
The alternative is to poll the ESXi Host through the vCenter server.
I think I might have found my problem. It looks like upgrading to NPM 12.0 was one step short of what I needed to do.VMware 6.5 support
Updated: October 17th, 2017
Unable to add or monitor VMware ESX/ESXi servers after upgrading to vSphere 6.5.
NPM 12.0.1 & SAM 6.3 and earlier
- NPM 12.0.1 & SAM 6.3 comes with iVIM 2.1.2 (or VIM 7.0 with vMAN), which only supports vSphere 6.0 and earlier.
- NPM 12.1 & SAM 6.4 comes with VIM 7.1.0, which supports vSphere 6.5.
I updated to 12.1 last night but no further since we are still on a 2008 SQL database. IVIM is still at 2.1.2 so I still can't log into my 6.5 hosts.
You can download the ivim 7 version and install on all poller and if you
have additional web server then also you can install, after installation
your issue will be fix.

I found this other thread while searching. It contains the VIM 7 download link.
Thread: NPM 12.0 and VMware 6.5
I will update again after the VIM install.
After updating to NPM 12.1 and VIM 7 (separate install) I was able to successfully test and use VMware 6.5 credentials and vCenter polling. NPM 12.1 is the last to support SQL 2008 so updating SQL in our environment will be one of the next projects.
