Due to ticket expiration, it is possible that the streaming channels for the client are created after the ticket expires. Currently, streaming channels are created dynamically when the guest starts streaming to the server, which can happen at any time (for instance if you decide to start the graphic server manually). If the ticket has expired before the streaming channel is created, authentication will fail and the client will not be able to connect. To avoid this, create the channels when the first main channel connection is made. This ensures that client will connect to all streaming channels. This could be considered a temporary solution. There may be other situations where it would be useful to connect new channels after the ticket has expired, but enabling this behavior would require protocol changes and a careful analysis of security implications.
