Snapshot deletion is in-progress

[alexus]

Hello World!

I'm trying to delete-snapshot by following: Create a snapshot | Elasticsearch Guide [7.17] | Elastic, yet per GET /_cat/tasks, this task is STILL running (it's been over 18+ hours now)

GET /_tasks/mUxakOw8T5iQhoXX7joG6g:20498983

  "completed" : false,
  "task" : {
    "node" : "mUxakOw8T5iQhoXX7joG6g",
    "id" : 20498983,
    "type" : "netty",
    "action" : "cluster:admin/snapshot/delete",
    "description" : "",
    "start_time_in_millis" : 1657143965154,
    "running_time_in_nanos" : 57612687226157,
    "cancellable" : false,
    "parent_task_id" : "VRyC7buqSpS51w6PYhAALQ:34097444",
    "headers" : { }
  }
}

GET /_tasks/VRyC7buqSpS51w6PYhAALQ:34097444

{
  "completed" : false,
  "task" : {
    "node" : "VRyC7buqSpS51w6PYhAALQ",
    "id" : 34097444,
    "type" : "transport",
    "action" : "cluster:admin/snapshot/delete",
    "description" : "",
    "start_time_in_millis" : 1657143965154,
    "running_time_in_nanos" : 57665217424333,
    "cancellable" : false,
    "headers" : { }
  }
}

I can't cancel the task due to "cancellable" : false, part.

Please advise.
