Same issue, but with Powercli 10.2 and Vsphere 6.5U2
I'll try opening a ticket next week.

get-tag : 9/7/2018 4:19:48 PM Get-Tag vSphere single sign-on failed for connection '/VIServer=xxxyyy:443/'. Future operations which require single sign-on on this
connection will fail. The underlying cause was: There was no endpoint listening at https://xxxyyypsc:7444/sts/STSService/vsphere.local that could accept the message. This is often caused by
an incorrect address or SOAP action. See InnerException, if present, for more details.
