SMB Connector not working in 4.6.1


I was just testing a old workflow of mine which writes a xlsx file to a windows share in our windows intranet.
The workflow is working fine with Knime 4.5.2 but somehow doesn’t work with 4.6.1 anymore.
When I try to access the share with 4.6.1, I get an access error


ERROR List Files/Folders   3:7        Execute failed: Unable to access \cash

I have access and right to the share and it still works with an old knime version 4.5.2.
I also can’t browse through the file system with 4.6.1 because of this error message. Writing does not work aswell

best regards,
