Network connection was lost error

I am trying to connect into realm object server from an app developed with swift on macos

When I try to connect, I get this error "Network connection was lost", but I can open the realm server from the browser without a problem.. btw, this problem happened recently, it was working correctly few weeks ago

let credentials = SyncCredentials.usernamePassword(username: username, password: password)

SyncUser.logIn(with: credentials, server: serverurl) {
            user, error in

            if let u = user {
                onCompletion(syncUser: u, error: nil)
            } else if let error = error {
                onCompletion(syncUser: nil, error: error)
            } else {
                onCompletion(syncUser: nil, error: nil)
            }
        }

Here, user is always nil and the error description is Network connection was lost

This happens with both a local server and one hosted on digitalocean

Server version 1.8.3

Edit 1: I have just enabled sandboxing to be able to upload the app into apple app store.. could this be the issue? any workaround?

Solution

  • It seems sandboxing was the real problem

    I had to enable Ingoing Connections and Outgoing Connections with sandboxing for this to work
