# v0 "Chat is Private" error for project owner and "Failed to submit message" in new chats

I’m seeing what looks like a `v0` chat ownership or permission bug.  

## Problem
I’m the owner of a `v0` project named `02ez`, but `v0` is showing:
> **Chat is Private. Ask the owner to update this chat’s sharing permissions.**

for my own project chat. At the same time, I’m also getting:
> **Failed to submit message**

in new and existing chats.  

The project itself still exists and the production deployment is healthy, so this does not look like a deployment outage. It looks like the issue is in `v0` chat access, workspace resolution, or session metadata.  

## Project Information
*   **Project:** `02ez`
*   **Production deployment:** Ready
*   **Deployment ID:** `8dd07b8`
*   **Deployment URL:** `02ez-oxwdv4vig-tostupidtooquit.vercel.app`
*   **Domain:** `tostupidtooquit.com`  

## Observed Behavior
*   I can access the project page
*   I cannot use the associated private chat even though I’m the owner
*   New chats can also fail with **"Failed to submit message"**  

## Expected Behavior
*   The owner should retain access to their own private chat
*   New chats should submit normally  

## Troubleshooting Done
1. Verified I’m in the correct account and workspace
2. Refreshed and retried
3. Started new chats
4. Confirmed the project and production deployment are still active  

I can share screenshots, URLs, and timestamps if needed for investigation.

Hi, I tried to reproduce this but couldn’t trigger it.

I tested multiple prompts, tabs, and sessions (including incognito), and everything worked normally. This suggests it’s not a general issue, but likely tied to specific account or chat state.

Given the symptoms (owner locked out, both new and existing chats affected, deployments still working), this looks like a backend mismatch between chat ownership, workspace, and session.

It might be worth checking chat ownership/workspace assignment and permission validation on message requests.

Hope this helps
