How to write to SQLite database from other fly.io app through LifteFS Proxy

This address seems incorrect. You can try (assuming it’s called app2):

  • app2.fly.dev if your app has services and public IPs, this will go through our proxy.
  • app2.internal:PORT if you want to bypass the proxy, but then you’d need to figure out your litefs port.
  • app2.flycast:PORT if your app uses auto stop machines you will not be able to use .internal domains when they’re stopped, luckily another customer found how to use flycast to solve this.

For litefs I’d recommend using our proxy (first option).
