The upstream API service timed out and no results were returned, please try again

Hey guys, I’m having a terrible issue while generating images using the nano banana pro API. The error I’m getting is “The upstream API service timed out and no results were returned please try again.” I use n8n for my automation.

I would appreciate any feedback from Google.

Hi @Amar_Rama , Thanks for reaching out to us.

Could you please provide an example of prompt you are using to generate images using nano banana pro along with the screenshot of error message? This will help us diagnose this issue effectively.

I’m also getting the same error. It was working before, but suddenly it started showing this message: “The upstream API service timed out and no results were returned, please try again.”

this is the prompt I use:

{
“input”: {
“prompt”: “Recreate the given image exactly, preserving its composition, subject, and overall visual tone. You must distinguish between content text and branding text based on the rules below.\n\nLayout & Style:\ni. Square (1:1 ratio), 1024x1024 or higher.\nii. Maintain a clean appearance consistent with the source image.\niii. Do not modify the core subject matter or composition.\n\nText Handling & Restoration (CRITICAL):\n1. CONTENT TEXT (RETAIN): Identify text that is part of the main message, caption, or joke of the image (e.g., meme header text in the white border, labels, or speech bubbles within the image). This text must be retained exactly as it appears in the reference. Replicate its original font, style, color, size, and precise position flawlessly.\n2. BRANDING/ATTRIBUTION (REMOVE): Identify text that serves only as branding, ownership, or attribution. This includes social media handles (e.g., text starting with ‘@’), “Posted by X,” URLs, website names, or copyright watermarks overlaying the image.\n3. INPAINTING: Completely remove all identified branding/attribution text. Seamlessly inpaint the area beneath the removed text to match the surrounding background, texture, or object, ensuring no trace of the watermark remains.\n\nImage Logic:\ni. Refer to the given image as the strict visual source.\nii. The final output should look like the original meme/image with its caption intact, but as if the branding watermarks were never applied.”,

Hey Sonali this is the prompt:

"Recreate this image with a fresh, modern, and creative visual style while keeping the same concept and the exact same text. You may change the layout, shapes, colors, and overall design to make it look new and unique. If the image is an illustration or infographic, redesign it with cleaner, more polished, contemporary graphics. If the image is realistic, regenerate it in a sharper, cinematic style with upgraded lighting, colors, and ambiance.”

Still we are facing big issues while trying to generate images.


Here is also the screenshot

Hi @Amar_Rama I have tried the same prompt you shared to generate an image with Nano Banana Pro on my end, and I was able to get a result without any timed out issue. I am attaching screenshot for your reference.

It might be a transient issue. Could you please try generating the image again now? If the issue persists, please let us know.
