I’m experiencing major & blocker issue on my end. All my api requests through Nano banana 2 a.k.a gemini-3.1-flash-image-preview are being failed with 500 status code for last 24 hours. I was wondering if anybody has faced such issue ? I don’t know how to address this and currently my ios app is not functioning due to this reason. I already implemented retry mechanism where the system waits for 1-2 seconds than try to initiate another request through gemini but all is failing as of now.
This is happening to me also. I am using a couple different Nano Banana 2 nodes in comfyUI with my API key and they all fail today with the 500 error. Switching to gemini-2.5-flash-image works just fine, so the NB Pro and NB 2 pipelines must be having issues. Generating NB2 content directly in Google AI Studio did work for me however, so it must just be a problem with the public API pathways? Very frustrating, I haven’t had a single request go through today in comfyUI.
Worth noting I also use the Astria Nano Banana 2 plugin directly inside photoshop, and I’ve received 4K results with 3.1 from them, so Astria must have a different pathway that’s working ok today since Astria has their own API.
Yes I’ve been having issues since late last night until about noon today. I stopped seeing errors around 12:00-1:00 EST. I did just a few minutes ago get a cluster of un-responsive requests with no errors provided but that subsided.
Agreed, I was able to observe same conditions, the NB 2 api does not works but if you try with ai studio thats fine. I’ve been using NB - gemini-2.5-flash-image since the morning as a fallback however that one also has issues like “Gemini API did not return image data“. Better than complete broken NB 2 api yet quite frustrating as I’m receiving a lot of complains from my users. I hope the folks from Google aware of the situation and address it soon.
I have the same problem with both NB 2 And NB Pro when using the API. In Google Studio using the same images and settings it works. I also exported the code from Google Studio, created a python file with the base64 image data included and ran it via the API and it fails with 500.
I noticed though that it only happens for images in 4K mode for me. If I use only up to 2K images it works now.
Got an even weirdest behaviour with this 500 status code with NB Pro since when I’m using my personnal gemini API key my queries are successfull. On another API key I’m using with my pro account, same input, same query, but got constantly 500 since Friday…
As of Monday morning from 9:30am until present time 1:30pm CST, 4K requests still do not work in my comfyUI workflow, and macOS Terminal delivers me this error:
503 UNAVAILABLE. {‘error’: {‘code’: 503, ‘message’: ‘This model is currently experiencing high demand. Spikes in demand are usually temporary. Please try again later.’, ‘status’: ‘UNAVAILABLE’}}
I am wondering if I would have better luck going the VertexAI route? Is this simply that standalone API users are getting cut off from this doorway when Google just can’t handle requests, in favor of companies using APIs that get to sneak through and use servers set aside for Enterprise users?
As of April 8 (today) I’m still getting connection refused errors from gemini api even with 2k option. It was happening randomly but I’ve observed several examples from today’s api requests. Since it’s becoming a quite frustrating experience I just need to know what is the plan for google to address it ? I may need to switch on different ai modal if it’‘ll keep happening so much frequently over time ..
Hi, just a little Update: I’ve now switched to using the Gemini Models via OpenRouter. And since they are a big customer, they seem to get a more stable connection When direct API fails for V2 and Pro with large images, it usually works via OpenRouter. It’s just a little bit more expensive.
