You're using the wrong port. It should be 9443 if you took everything by default. So use https://wasrtc02:9443/jts/admin instead of https://wasrtc02:9043/jts/admin
To double check, log on to WAS admin console (or Integrated Solutions Console as you call it) and navigate to Environment > Virtual hosts. You should see two entries there - admin_hosts and default_host. Select either of them and examine "Host Aliases" for the associated ports.
Next navigate to Applications > WebSphere enterprise applications > jts and examine Virtual hosts under Web Module Properties. You want you web application to be mapped to "default_host" only unless you know a specific reason not to.
Finally, in the SystemOut.log file, you should be able to locate such a line as "WSVR0200I: Starting application: jts" (or jts_war depending the name you gave when deploying the web application). A few lines down, and just above "WSVR0221I: Application started: jts",  in the same log file, you should see a line like this:
com.ibm.ws.webcontainer.VirtualHostImpl addWebApplication SRVE0250I: Web Module null has been bound to default_host[*:9080,*:80,*:9443,*:5060,*:5061,*:443].
In the sample above, 9080 and 9443 are the ports that you can use to access the web application on the WAS profile directly, and 80 and 443 with IHS rerouting.
