I am not able to connect to remote `zOS DB2` with python `ibm db` package.
while connecting I am getting below error:

```
: [IBM][CLI Driver] SQL30081N  A communication error has been detected.
Communication protocol being used: "TCP/IP".
Communication API being use d: "SOCKETS".
Location where the be error was detected: "HOSTNAME".
Communication function detecting the error: "recv".
Protocol specific error code(s): "104", "*", "0".  SQLSTATE=08001`

```

How can I solve this error?.

Just to add firewall is open.
Telnet and openssl is working fine.
