GameLiftLocal Fails to start with Exception

Hi,

I'm trying to test Unity game server with GameLiftLocal

Using the GameLift Plugin for unity Local Testing window -> Deploy & Run

The program fails on : var initSDKOutcome = GameLiftServerAPI.InitSDK();

Error :

AM|Fatal|WebSocket.connect|System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it.

InitSDK failure : [GameLiftError: ErrorType=LOCAL_CONNECTION_FAILED, ErrorName=Local connection failed., ErrorMessage=Connection to local agent could not be established.]

When running GameLiftLocal manually : java -jar GameLiftLocal.jar -p 8000

Exception :

What can be the cause for this problem ?

I also tried with an Older version of GameLiftLocal, same error
