Maybe, but I can't tell for sure.   I use the container almost the same but I use --key _ but that shouldn't make a difference since it does the same.   Are you sure that you've specified your key in your client. What you are describing is not possible usually. However IIRC if you tried it first without a key and after that create a key and then connect to the server then it is possible that the client that tries to connect is cached on the server <- but I'm not sure
