We hit an intermittent local-dev issue where the browser became “dead”: navigation stopped working and all same-origin API requests showed Pending in DevTools.
First request to get stuck was a long-lived request named console-pipe. After that, most other requests to the same origin were stuck pending
The app works fine when deployed, so it's a dev-only issue.
What fixed it:
Disabling TanStack Devtools “server bus” connection stopped console-pipe from being created and immediately fixed the issue.
@tanstack/react-devtools with eventBusConfig: { connectToServerBus: true }
@tanstack/devtools-vite and tanstack/react-ai-devtools plugins enabled

I understand that if my bug cannot be reliable reproduced in a debuggable environment, it will probably not be fixed and this issue may even be closed.
I was viewing the issue in the chrome devtools. The app was also dead on
safari. The symptom was that the entire app was dead. Could not navigate at
all. If I killed vite server and restarted I could load a single page.
I will check it out, thank youOn Feb 7, 2026, at 5:44 PM, Alem Tuzlak ***@***.***> wrote:AlemTuzlak left a comment (TanStack/devtools#342)
