Problem with Get-Tag and Get-TagAssignment

All of a sudden I get errors in my existing scripts which use Get-Tag or Get-TagAssignment.

This is the error:

get-tag : 19/10/2017 15:15:20 Get-Tag vSphere single sign-on failed for connection '/VIServer=domain\admin@vcenter.domain.local:443/'. Future operations which require single sign-on on this connection will fail. The underlying cause was: The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

Whenever I search for the error, I only see resolutions for WCF applications/services...
