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

Answer 1

I did not get how did you connect. Please, try the following to help us to understand from where are you coming from:

import ibm_db
ibm_db.connect("DATABASE=;HOSTNAME=;PORT=;PROTOCOL=TCPIP;UID=;PWD=;", "", "")

Answer 2

I am able to connect to the remote zOS DB2 using below connection string:

import ibm_db

ibm_db.connect("Security=SSL;database=dbname;hostname=hostip;port=port;Protocol=TCPIP;SSLClientKeystoredb=pathtothekeystoredbfile(file extension.kdb);SSLClientKeystash=pathtothekeystashfile(file extension.sth);uid=userid;pwd=password", "", "")

Also, I had to put the licence file "db2consv_zs.lic" to the LICENSE folder of ibm_db.
