Ruan,
KB article 145355 is very relevant to the problem. It identifies the common problems related to the connection error you're receiving.
I assume this was working at one point and something has changed. Given that, let's look at the most common configuration problems.
- CSAM configuration on both client (WCC) and application server machines must be configured the same. This can be reviewed using 'csamconfigedit port=9000 display' command. The EnableSSL and EnablePmux settings are config settings customers most frequently change. Port 9000 assumes that this is port specified in the AutoSys $AUTOUSER/config.$AUTOSERV file for the AutoServerPort setting.
- Assuming CSAM EnablePmux=True is set, TCP port 7163 is used for communication, by default. The port used can be confirmed by looking at the global configuration, 'csamconfigedit display'. This port must be open to through the firewall to both machines.
- Network routing. Both WCC and App server machines need to be able to connect. This typically can be verified using OS ping command.
Assuming this was working at one point and the AutoSys/WCC configuration wasn't changed my guess would be this is a firewall issue.
Please review the KB article and the items listed above to see if this helps.

Subject: Communication attempt with the CA WAAE Application Server has failed
Hi all
We are running an AE server with WCC connected as well as EEM. AE is version 11.3.6 SP8. The landscape was commissioned by CA implementation consultants who have now rolled off the project.
Currently the AE server is still up and running and thankfully still running SAP workloads but WCC cannot connect and for example running autoping or autorep on the AE server itself results in the error message below:
CAUAJM_E_10029 Communication attempt with the CA WAAE Application Server has failed! [stwprdvsaae01.internal.isuzu.co.za:9000]
CAUAJM_E_10221 Exhausted list of available Application Server(s). Failing request.
CAUAJM_E_50033 Error initializing tx subsystem: CAUAJM_E_10062 Failed to get initial configuration from CA WAAE Application Server(s).
I can see the below messages for example in csam.log on the AE server:
Thu Feb 27 16:14:17.109 WARN CSAM.BROK [4146657600] [4131] [2] processAcceptRequest: - caller [::ffff:10.91.0.18]:50440 wants us to connect to port 9000. No client available

In the above example the .18 IP is the WCC server.
Any suggestions or ideas? I have opened a support case but to date no working solution was offered. I was directed at article 145355 but I do not think that is relevant. I may be wrong...
