After updating to the new v.1.16.5 on Linux Antigravity can no longer connect to devcontainers and shows ‘Could not fetch remote environment. Failed to connect to the remote extension host server (Error: WebSocket close with status code 1006)’. Here’s the tail of the output logs: # Finish server s…

I was really frustrated with this issue, too. I spent the better part of the last 2 days trying to find the problem Had Gemini to summarise the bug, cause and a potential hack until Google fixes this properly Have still not managed to get Docker in Docker working, though Hope it helps some of you…

Thank you @Ashwin_Krishnan you save my day.

Still bugged with container from mid january. I’ve reported the bug to google on many different communication channels. No feedbcak. No hot fixes. Google team, you can’t lag behinds like this for paying customers. There’s already enough complains about silly black box quotas, we deserve at least …
