Got it fixed, thanks to Troy.
Watch the next release of his check if you encounter a similar issue.

Note: was due to one of our servers not responding correctly and the script stopping because of the failure. So if you do have this issue: check your hosts manually in the vsphere web console and see if you get any errors accessing the hosts information page. If you do: fix it

Thanks for the feedback, Unigarant! I am glad your issue has been resolved! I will be closing this topic now. If you have any more questions/issues, please start a new thread.
