Something went wrong. Please try again later.

I'm trying to create images with Gemini Nano Banana and often, it doesn't generate the image and displays the following message:

"Something went wrong. Please try agin later.".

I tried last night and it didn't work, and now, this morning, it doesn't work either. It’s not the first time it happens. It's frustrating because I have credits to use before they expire in a few days and if I can't use them, I lose them.
