Sharepoint 2010 Content Type Hub Error – No valid proxy can be found to do this operation
By peter.stilgoe
If you have changed your URL for your Sharepoint 2010 farm you will get the error:
‘No valid proxy can be found to do this operation’
when trying to publish new content types from the content type hub.
This is because the URL in the managed meta data service application needs to be updated to reflect the new URL change. You can do this by running the following Powershell script:
Set-SPMetadataServiceApplication -Identity "Managed Metadata Application" -HubURI "http://NewSharepointURL"
