Hi @이상언 — welcome to Figma Forum, and thanks for flagging this.
We don't currently offer support in Korean on the forum, so I hope it's okay that I'm replying in English.
Based on what you reported and the error message in your screenshot, it looks like Figma Make is running into a connection issue across all models. Here are a few things worth trying:
Check your connection: Make sure you're connected to the internet, then try your prompt again.
Try a different network: If possible, switch to another Wi-Fi or mobile connection and see if that makes a difference.
