Could not locate storage service from https://app.elm.com:443/jts/rootservices. Make sure that server property Public URI Root is correct

Hi guys,

During jts/setup I am finalizing the RM application, during the Perform User Synchronization step I am getting the error:

Error 500: Propagated exception; original message [InternalServerErrorException: com.ibm.rdm.fronting.server.exception.InternalServerErrorException]

In the rmExt.log it dumps several:

Could not locate storage service from https://app.elm.com:443/jts/rootservices. Make sure that server property Public URI Root is correct.

And then it dumps:

com.ibm.team.repository.common.TeamRepositoryException: Could not locate storage service from https://app.elm.com:443/jts/rootservices. Make sure that server property Public URI Root is correct.

If I curl https://app.elm.com:443/jts/rootservices from the server I get the specified xml document. There is an entry there for <jfs:storage rdf:resource="https://app.elm.com/jts/storage"/>

The server is sitting behind a reverse proxy. The reverse proxy forwards 443 -> 9443.

There is another JTS running behind the reverse proxy which was set up fine.

The public URI is correct, I have set this with the jts/setup GUI and it resolves.

Can anyone provide any help? The server can resolve the URLs it is asking for I am not sure why it's getting a 500 error when syncing the users? Why can't it find the storage
