Plugin download link

I tried to call the url:

https://acpt.io/wp-json/api/v1/plugin/download?license=xxx&user_id=yyy

Request:

{
  "method": "GET",
  "timeout": 300,
  "redirection": 5,
  "httpversion": "1.0",
  "user-agent": "WordPress/6.1.1; https://acpt.io",
  "reject_unsafe_urls": true,
  "blocking": true,
  "headers": [],
  "cookies": [],
  "body": null,
  "compress": false,
  "decompress": true,
  "sslverify": true,
  "sslcertificates": "/home/acptio/public_html/wp-includes/certificates/ca-bundle.crt",
  "stream": true,
  "filename": "/tmp/download-IDNeoh.tmp",
  "limit_response_size": null,
  "_redirection": 5
}

I got this response:


```{
  "headers": {},
  "body": "",
  "response": {
    "code": 503,
    "message": "Service Unavailable"
  },
  "cookies": [],
  "filename": "/tmp/download-IDNeoh.tmp",
  "http_response": {
    "data": null,
    "headers": null,
    "status": null
  }
}

If I call the same URL by curl or by calling it via browser, the file is correctly downloaded.

Any ideas?
