Because of the Error message in headline that we got in TDoD Config Editor (in Configure Portal tab), we are not able to make the Datamaker, ARD, Javelin utilize the Service Layer integration.

We tried all resolutions mentioned in the below links, but none of them seem to be resolving the above issue.

We are seeing the following error in GT Datamaker: Unable to connect service layer

Release:
Component: TDMTDD

When using the TDoD Configuration Editor to configure the TDoD service, in the "Configure Service" Tab, verify the connection information for the gtrep Repository Database is correct.

Also verify that the  Advanced Setting Tab - Service Base Address has not been modified. It should be http://*:8090/ by default. Changing this address to http://<localhost>:8090/GTService has been known to cause this type of issue. 

If the Advanced Setting Tab - Service Base Address has been modified:

1. Change it back to http://*:8090/ 
2. Save the changes to the configuration
3. Stop the TDoD service from within the TDoD Config Editor utility - Configure Service Tab
4. Restart the TDoD service from within the TDoD Config Editor utility - Configure Service Tab
5. Verify the connections have been resolved

**NOTE**
We have seen odd behavior when the Advanced Setting Tab - Service Base Address contains a typo, such as http://*.8090/. In these instances, the TDoD service will start, and appears to be running as normal, however the Listener port on 8090 fails open. Therefore, connections will still fail. If you run a "netstat" command and do not see the Listener port open on 8090, please verify the Advanced Setting Tab - Service Base Address is correct, and no typos exist.
