I am using the service discovery (Python) example. It works for some time (a few minutes) before failing with response below:

RECEIVED on session1:
[
  {
    "Domain":"Login",
    "ID":1,
    "Key":{
      "Elements":{
        "AuthenticationErrorCode":1026,
        "AuthenticationErrorText":"Request for token validation failed:Authentication server did not contain \"active\" in response"
      },
      "NameType":5
    },
    "State":{
      "Code":"UserAccessToAppDenied",
      "Data":"Suspect",
      "Stream":"Closed",
      "Text":"TREP authentication failed (1026, Request for token validation failed:Authentication server did not contain \"active\" in response)."
    },
    "Type":"Status"
  }
]

Please advise
