Hello, I have a MySQL database and Node.js running on Railway. My frontend is hosted on Netlify. Actually, when I test, everything is working very well, but after some time the backend crashes, no data is being shown and i can't access the backend with with the Public Networking-Adress. When I redeploy, everything works perfectly again.

Here is the error:
node:events:495

throw er; // Unhandled 'error' event

^

Error: Connection lost: The server closed the connection.
