Gpt-4-vision-preview very slow responses

Anyone else having very slow responses or no response at all from gpt-4-vision-preview? I got it working the first few times, but it seems to be hanging now, no response even after 5 minutes.

const base64String = await downloadImage("https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg")


  const response = await openai.chat.completions.create({
    model: "gpt-4-vision-preview",
    messages: [
      {
        role: "user",
        content: [
          { type: "text", text: `What's in this image? ` },
          {
            type: "image_url",
            image_url: {
              "url": `data:image/jpeg;base64,${base64String}`,
              // url: "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg"
            },
          },
        ],
      },
    ],
    max_tokens: 4096,

  });

async function downloadImage(url: string): Promise<string> {
  const response = await fetch(url);
  const buffer = await response.arrayBuffer();
  const base64data = Buffer.from(buffer).toString('base64');
  return base64data;
}

Running in NodeJS

the API is working now, it was down for about an hour, tried again and it works!
