IZE0106E Connection timed out when using OpenText SOCKS Client

Question & Answer

Question

Why does the CICS Explorer fail to connect to the host with error "Connection timed out: connect" when using OpenText SOCKS Client?

The .log shows :

 !ENTRY com.ibm.cics.core.connections 2 2 2019-03-01 10:10:54.781
 !MESSAGE IZE0106E Connect failed with error "Connection timed out: connect" (HOST XXX)

Answer

OpenText SOCKS Client automatically intercepts requests and pushes them through the correct socks proxy. So, there is no proxy configuration.

This is because of the way Java operates with IPv6. For more information, see Java applications no longer socksify correctly.

To fix this problem, add the following line at the end of the zosexplorer.ini file (somewhere under the -vmargs line):

-Djava.net.preferIPv4Stack=true
