Can't get a back link to Server 2 RM
One answer
_QfDrMdIKEeKWdeCnc9A2rA: is the UUID of the project area. It seems that whatever project area you are linking to, may not exist any longer. Can you confirm it still resides on the jazz.net sandbox? If it does, open up the project area and confirm that the UUID matches the error message. If it doesn't try using the new UUID when updating the link.
