I understand that you're encountering an error when trying to connect the wallet. This error occurs when a user rejects the wallet connection request. Let's update the Header.tsx file to handle this error more gracefully and provide a better user experience.

These changes will improve the error handling in your application:

1. We've added a specific error message for when the user rejects the connection request (error code 4001).
2. We're resetting the connection state (setIsConnected(false) and setWalletAddress("")) if there's any error during the connection process.
3. The error message is now displayed more prominently below the "Connect Wallet" button.

With these updates, when a user rejects the wallet connection request, they'll see a clear message asking them to try again. This should provide a better user experience and make it easier for users to understand what happened if they accidentally reject the connection request.

If you encounter any other issues or need further modifications, please let me know!
