A process / program should open/create a socket and bind it to an ip interface/port for listening. , then we can connect to it right.
In your case, may be reach out to basis to start a program/process which listens on that port first, then it accepts connections on it.

Can you please confirm that your OS is listening to port 31015 or not by running below command.

netstat -ntlp |grep 31015

If its not listening then you will not be able to connect to that port.

Tell me your actual problem. You think that because of this telnet problem you are not able to connect to HANA but tell me when you are facing this issue. While connecting to Hana Studio ?

Also make sure that below mentioned your Major Hana service is running or not you can check that by "HDB info" command

hdbnameserver
 hdbcompileserver
 hdbpreprocessor
 hdbindexserver
 hdbwebdispatcher

This will give you idea.
