Unable to use RemoteUIStatsStorageRouter

[aeiplatform]

Issue Description

I was unable to use the remove stat listener for the latest version.
Has the use been changed in any way or is this a mistake?

Server:

UIServer.getInstance().enableRemoteListener();

Client:

new StatsListener(
    new RemoteUIStatsStorageRouter(UI_HOST)
)

Version Information

• Deeplearning4j 1.0.0-M2.1

@aeiplatform do you have anything from the server? This unfortunately doesn't actually give me the reason for the 500 error.

[aeiplatform]

Doesn't seem to be logging anything even when they're on the same server.
Maybe it's relevant #10055

Because after I killed the process:
