Stuck with CH_CTID_TRADER_ACCOUNT_NOT_FOUND error

Hi folks,

I'm trying to play with java-sample-connect  ; after some difficulties, I can now run my app, authorization request went well, but I stuck with this message when I try to subscribe or to send market order :

sendSubscribeForTradingEventsRequest() Message to be send:

ProcessIncomingDataStream() Message received:
ProtoMessage{ErrorResponse{errorCode:CH_CTID_TRADER_ACCOUNT_NOT_FOUND, description:Unable to find cTID trader account with id=xxx}}

if I understand well this message, the API is unable to recover back my cTID with my trader account id. 

but if I go to https://sandbox-ctweb.spotware.com/ with my trader account id, it appears to be successfully connected to my ctidXXXXX

What went wrong ?

some informations :

- ctID created on https://sandbox-connect.spotware.com, then application created with correct clientID, secretID, and returning well an access_token
- trader account id and link to ctID gone with https://sandbox-ctweb.spotware.com/
 

thanks in advance !
