ConnectPort LTS 32 - ports 17-32 are not responding to Telnet connections

I have ConnectPort LTS 32 with 32 ports.
to ports 1-16 i can successfully get a telnet connections but to ports 17-32- it looks like it is not responding. the configuration was copied from one of the ports 1-16, so if it worked for me in these ports it should be the same also for the upper ports (17-32).

am i missing something? doesn’t make sense that the complete row won’t get any connection…
