TypeError: fetch failed (UND_ERR_CONNECT_TIMEOUT)

[HNCODE]

Nodes: [
{
name: "1",
url: "1",
auth: "1",
},
{
name: "2",
url: "2",
auth: "2",
},
{
name: "3",
url: "3",
auth: "3",
},
{
name: "4",
url: "4",
auth: "4",
}
],

That's how it's working right now.
The function is working properly now, but the "fetch failed" error is constantly popping up. What's wrong?
Whenever an error appears, the song stops due to the corresponding "Node".
