iControlREST - 404 for any RESTful request. - BIGIP 11.5.3 HF2

Hi All,

Receiving this from one of two devices in a pair. (Other working fine).

{
  "code": 404,
  "message": "http://localhost:8100/mgmt/tm/sys",
  "restOperationId": 8279793,
  "errorStack": [
    "com.f5.rest.common.RestWorkerUriNotFoundException: http://localhost:8100/mgmt/tm/sys",
    "at com.f5.rest.common.RestServer.trySendInProcess(RestServer.java:231)",
    "at com.f5.rest.common.RestRequestReceiver.dispatchToService(RestRequestReceiver.java:93)",
    "at com.f5.rest.common.RestRequestReceiver.processNext(RestRequestReceiver.java:57)",
    "at com.f5.rest.common.RestHelper$2.run(RestHelper.java:1910)",
    "at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)",
    "at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)",
    "at java.lang.Thread.run(Thread.java:722)\n"
  ]
}

I've tried restarting the restjavad service, which has restarted but makes no difference.

I am authorized correctly and the same query to it's counter part works.

Any ideas?

Many thanks,

JD
