Sometimes the `-c` is not work

[Rory-Z]

I'm using emqtt-bench-0.4.11-ubuntu22.04-amd64-quic.tar.gz in AWS EC2

and when I'm running ./bin/emqtt_bench pub -h 10.11.7.83 -p 31883 -t 't/%i'-c 10000 -k 300 -l, looks -c is not work, the connect_succ is keep 200.

but if I'm running ./bin/emqtt_bench pub -c 10000 -h 10.11.7.83 -p 31883 -t 't/%i' -k 300 -l, the -c is work.
