fireqos doesnt match concurrent connections

[Ma Ke]

Hello Everyone,I need some help with my fireqos configuration.I have a ubuntu server sourcing RTSP stream on port 2554.I have configured QoS as follows:
DEVICE=eth0
INPUT_SPEED=9000kbit
OUTPUT_SPEED=9000kbit


interface $DEVICE world-in input rate $INPUT_SPEED balanced
        class rtsp                               
                match tcp dports 2554
        

        class vpn
                match udp dport 1194

interface $DEVICE world-out output rate $OUTPUT_SPEED balanced
        class rtsp
                match tcp sports 2554

        class vpn
                match udp sport 1194
The first connection to  the stream will be matched and put into the right class.

If I connect to the RTSP stream with another client. the connection will go to defaultubuntu at ip-172-31-5-92:/etc/firehol$ sudo fireqos status world-out
