Antigravity agent not responding

Hey so I am paying for AI Ultra for Business, yet I am regularly facing issues. Sometimes “high traffic” issues pop up on every request, even though the AI Ultra description claims priority request processing and what not.

Today it just stopped working altogether. Any messages I send just don’t result in anything. Neither in the agent manager, nor in the side bar. The message just goes to the top and just.. sits there doing nothing. I tried logging out but then could not login. I tried downgrading to 1.20.6 by going version by version but that only allowed me to login. On 1.20.6 it says “unsupported version, upgrade to continue using”

When i tried to submit a bug report it kept loading endlessly. Could not submit

It is disappointing, because I am paying “business” price for a product that barely works. If this is not fixed in a few hours, I am considering dropping a lot of licenses and stuff we currently pay for on our workspace and associated accounts.

Title: Solution: Antigravity AI Agent not responding / “connectex” timeout on Windows behind a proxy

Hey everyone,

I recently ran into the notorious “dead silence” issue where the Antigravity Agent stops responding completely. Checking the logs revealed connectex timeout errors (Language server… dial tcp… failed to respond).

The Root Cause:
The underlying Go-based Language Server (server.exe) often ignores system proxy settings and even the IDE’s built-in Http: Proxy configuration.

The Solution (Using Proxifier for process-level routing):
Instead of using TUN mode, you can use Proxifier to intercept the specific Antigravity processes and force them through your local SOCKS5 proxy.

Here is the step-by-step fix:

Step 1: Clear internal settings

Open Antigravity Settings.

Clear the Http: Proxy field (leave it blank).

Uncheck Http: Proxy Strict SSL.

Close Antigravity completely.

Step 2: Configure Proxifier

Add Proxy Server: Go to Profile → Proxy Servers, add your local client’s SOCKS5 proxy (e.g., 127.0.0.1 port 7680, protocol SOCKS5).

Fix DNS Pollution: Go to Profile → Name Resolution, and enable “Resolve hostnames through proxy”.

Setup Rules: Go to Profile → Proxification Rules and set up the rules in this exact order (from top to bottom):

localhost → Direct

antigravity.exe; server.exe; gopls.exe → Proxy SOCKS5 127.0.0.1 (This forces the IDE and the hidden Language Server to use the proxy).

Default → Direct (Ensures your other normal PC traffic is unaffected).

Once saved, keep Proxifier running in the background and restart Antigravity. You should see the traffic routing successfully in Proxifier, and the AI ​​Agent will instantly come back to life.

Hope this saves someone hours of debugging!
