I have a fetch request but it doesn't seem to expire? At leats when i refresh the page 10 mins later it doesn't revalidate. (The endpoint its hitting was online, now offline so is returning ECONNREFUSED)

In dev mode if it helps

    const res = await fetch(`http://localhost:3005/abc`, {
      next: { revalidate: 30 * 1000 },
    });

In the .next fetch-cache folder

{
  "kind": "FETCH",
  "data": {
    "headers": {
      "connection": "keep-alive",
      "content-length": "39",
      "content-type": "application/json; charset=utf-8",
      "date": "Thu, 04 Jan 2024 09:45:28 GMT",
      "keep-alive": "timeout=5"
    },
    "body": "....",
    "status": 200,
    "url": "http://localhost:3005/abc"
  },
  "revalidate": 30000,
  "tags": []
}
