Multi-player Tic-Tac-Toe Not Working After Deployment

**Description**:
The multi-player Tic-Tac-Toe game, located in the folder `game/tic-tac-toe/multi-player`, is not functioning correctly when deployed on Vercel. The game works fine on my local system but breaks after deployment.

**Expected Behavior**:
The game should allow users to join, make moves, and determine a winner in real-time without issues.

**Actual Behavior**:
- The game either does not start or fails to handle player moves after deployment on Vercel.

**Environment**:
- Local System: Works as expected.
- Vercel Deployment: Issue occurs.

**Additional Information**:
Please check if there are any environment variable configurations, socket connection issues, or deployment settings that might differ between local and Vercel environments.
