We have these errors happening only occasionally and I'm not able to reproduce these errors.

1. Is it possible to retry only when errors are network errors: https://github.com/sindresorhus/is-network-error/blob/main/index.js ?

2. Does anyone know what causes these errors? Is it normal to explicitly catch and handle these specific errors or is it more likely a problem on my app or server? The server is just a Hetzner VPS with very basic configuration, I can't imagine it being that with the popularity that Hetzner has; as to the app, it only happens very occasionally, the same request will succeed after any subsequent attempt.
