Builds and deploys for Hobby plans are temporarily paused while we recover from a platform-wide issue. Your deploy attempts are being rejected because of this pause, not anything on your end. You can follow progress here: https://status.railway.com/incident/KVZ1Z8GY. Once the pause is lifted, you'll need to redeploy your services manually. In the meantime, avoid queuing additional deploys as they will compound the backlog.
