Using K2 connect Administration tools, "K2 blackpearl settings":
SmartObject Server Exception: Error refreshing Service Instance 'ConnectService'. Service returned : 'Object reference not set to an instance of an object.
 

Diagnoses

Using SAP Logon we found: "Nombre tentative incorr. connection av. mote de passe : 1 (texte descr.)", but just after this popup, we can access to SAP content.
