When getting a 'Connection failed' message at the SMPE Internet retrieval to get the latest maintenance downloaded and possibly received in your product CSI, it can have multiple causes and possible solutions...
Most of the time it is a connection issue with our servers because of firewall/proxy settings...
How can you trace an debug the connection and what are the possible solutions.
Release : 15.0
Component : CCS390 - CA COMMON SERVICES FOR Z/OS
The first thing to do is to check the Network configuration...
See his special chapter in the manual :

If this doesnt solve the issue, then add these 2 statements to the SMPE Receive order job :
-Djava.security.debug
-Djavax.net.debug
Like this :
<CLIENT
downloadmethod="https"
javahome="/C/java/java64bt/v8r0m0/usr/lpp/java/J8.0_64"
classpath="/usr/lpp/smp/classes"
javadebugoptions="-Dcom.ibm.smp.debug=severe -showversion
-Djava.security.debug
-Djavax.net.debug">
</CLIENT>
If that doesnt show the error, it's possible there is still an issue with the firewall/proxy server settings and it's possible to add an additional HTTP Proxy statement..
