Been having the same issue on Debian. Tried reinstalling that did not work. Tried purge remove and then refresh. Nothing!

LukasdeSouza · February 9, 2026, 6:59pm

Same issue here. How to solve it ?

esdrascastro · February 9, 2026, 7:03pm

Same issue and no one to say what is happening.

SamuAranguren · February 9, 2026, 7:06pm

Same here on Windows 10

Mister_Crowne · February 9, 2026, 7:10pm

Suddenly started having this issue as well. It happened almost immediately after I turned off Tab suggestions/autocomplete, not sure if it’s related or not. But now even after turning it back on, these errors fire repeatedly every few seconds.

Nicola_Damian · February 9, 2026, 7:13pm

Happens to me as well. Win 11

Trevisan · February 9, 2026, 7:16pm

Here too, on Ubuntu 22. Downdetector is also reporting problems with Gemini. It might be related.

Lucas_Gomes · February 9, 2026, 7:19pm

Same here, windows 11.

Joining the club – after weeks of working now this error on Windows 11. Nothing I tried worked. I guess the issue is not on my side.

IvanQ · February 9, 2026, 7:24pm

Same here, on macOS, latest Antigravity Version: 1.16.5.

Marcio_Lourenco · February 9, 2026, 7:32pm

Estou com o mesmo problema, estranho que somente descloguei e loguei com outra conta do google no Antigravity, e nessa outra conta não apresenteou problmeas .

jag2kn · February 9, 2026, 7:36pm

El mismo error en Ubuntu 24.10

Realicé reinstalación con purge y eliminación de archivos .gemini y .antigravity.

Posteriormente realicé la reinstalación y está funcionando por el momento.

Roberto_Mundo · February 9, 2026, 7:45pm

I solved it using Gemini

If you are getting the Error: connect ECONNREFUSED 127.0.0.1:... and trying to fix it via terminal (using sudo xattr or chmod) results in a long list of xattr: [Errno 1] Operation not permitted, stop trying to force it via terminal.

This happens because macOS (especially on M3/M4 chips and Sequoia/Sonoma) has flagged the app’s internal binaries as compromised/corrupted, locking them down at the kernel level. Even sudo cannot bypass this.

The Solution (Takes 2 mins):

Delete: Move the Antigravity app to the Trash and Empty the Trash (This is critical to clear the security flag).
Download: Get the latest Apple Silicon version from the official site.
The Secret Step: Do not double-click the app to launch it for the first time.
- Right-Click the app icon.
- Select Open.
- Click “Open” on the system dialog.

This forces macOS to re-verify and whitelist the new binary signatures, allowing the local server ports to open correctly.
