During VNF Restart APPC made a token request to MultiCloud utilizing the v2 token request.  The request seems to be accepted by MultiCloud but the payload containing the auth info for v2 was rejected (log entries below).  The request was made in the vCPE Integration lab(APPC 10.12.25.50).

MultiCloud error when trying to connect using v2:
