fix: Ensure error message is displayed when connection fails

- Added logic to remove the "hidden" class from the room list container when a connection error occurs.
- This change ensures that the error message is correctly displayed when there is a connection failure.

This fix improves the user experience by providing clear feedback when a connection error occurs.
