Appears the server is disconnecting the peer, though there is currently no timer showing on the server. The timer should be on the client side for dropping the connection. The timeout var should be configurable by the user, so a user can wait 30 min or more before falling back to solo mode. Error messages text being displayed should be more explicit with detail and checked for accuracy.

Client should also have an option for if it should fall back to solo mode or just cancel the purchase.
