Hi everyone,

I’m seeing the Antigravity agent failing to send prompts on my PC. It was working a few hours ago on my personal Wi-Fi, but now every prompt returns “fail to send”. I’ve already tried:

  • Restarting the agent and PC

  • Checking firewall/antivirus (Windows Defender)

  • Deleting local config/session

  • Switching networks

Despite all this, it still fails.

Hello @Okelo0121, welcome to AI Forum!
I just sent messages to GPT-OSS 120B (Medium), Gemini 3.1 Pro (High) and Gemini 3 Flash in my Antigravity setup with latest version and got responses.
Could you please upgrade Antigravity to the latest version from Antigravity download page and let us know if the issue persists?
