Recived token not working

Hello,

We are having a problem with the connection token.

Some times, when we get the token from refinitiv we get rejected:

Getting the token:

{
  "Domain":"Login",
  "ID":1,
  "Key":{
    "Elements":{
      "ApplicationId":"739590397752477c9d02dde57af75cf77f98b680",
      "AuthenticationToken":"eyJ0eXAiO...

Error:

[
  {
    "Domain":"Login",
    "ID":1,
    "Key":{
      "Name":"AQIC5wM2..."
    },
    "State":{
      "Code":"Error",
      "Data":"Suspect",
      "Stream":"Closed",
      "Text":"Login Denied:Failed to lookup sso token - AQIC5wM2..."
    },
    "Type":"Status"
  }
]

[
  {
    "Domain":"Login",
    "ID":1,
    "Key":{
      "Name":"AQIC5wM2LY4SfcwgOg%2BShT6xwuDp%2F3uHT7p%2FVYezE8RTGHQ%3D%40AAJTSQACMTAAAlNLABQtMjIzNDM1ODM4NjMzOTgwMTMyNQACUzEAAjI4%23"
    },
    "State":{
      "Code":"Error",
      "Data":"Suspect",
      "Stream":"Closed",
      "Text":"Login Denied:Failed to validate sso token"
    },
    "Type":"Status"
  }
]

If we reset the connection, it works fine.

This is happening randomly, most of the times do not happen actually.

Any ideas why this is happening?

Thank you,
