Hi, I new here

I just set up Notify To Discord on my Rust Server. I've followed the documentation, but when I load the plugin I got this :

[Notify To Discord] Discord Api responded with 429: {
  "global": true, 
  "message": "You are being rate limited.", 
  "retry_after": 782
}

I use Discord Webhooks. I need your help. Thanks

And the other one :

[Notify To Discord] Discord Api responded with 401: {"message": "401: Unauthorized", "code": 0}
