How to get telnet working on Solaris 11

Hi All,

I have a specific issue on my server. ssh is working but telnet doesn't. Although system administrator has now enable telnet so telnet is working on server but has issues while trying to access it with port. For example in my case

telnet localhost (works)

telnet ip (works)

telnet remote_ip (works)

But when I try it with port it doesn't work.

telnet localhost 9704 (doesn't work)

telnet ip 9704 (doesn't work)

telnet remote_ip 9704 (doesn't work)

Admins from bank are ahving tough time finding resolution for this and it is pending for a week now.

When app team hits report from Flexcube application they are seeing below error .
