Dears,
I've met issue with re-connection to database. Time by time re-connection is unsuccessful with this error message: "Firebase.Database.Internal.TubeSock.WebSocketException: IO Exception ---> System.IO.IOException: IO exception during Write. ---> System.ObjectDisposedException: The object was used after being disposed."

Please check the log for more detalies:

Hi -- would you be able to give a few more details on how the disconnect and reconnect is happening?
are you turning on airplane mode, calling GoOffline(), etc?

Hi, I'm using example from quickstart-unity-master\database\testapp. With some minor changes in UI.

I'm getting this issue only on android phone Lg G3, not on PC.

In one session I have a multiple disconnection and auto reconnection (screenshot attached). I do not call GoOffline(), the reason of this disconnection I beleive unstable Internet connection or some other thing related to internal library logic.

This code shows connect|disconnect events:

FirebaseDatabase.DefaultInstance.GetReference(".info/connected").ValueChanged = Chat_ValueChanged;

private void Chat_ValueChanged(object sender, ValueChangedEventArgs e)
{
    Debug.Log(e.Snapshot.Value);
...
}

It's work fine till I get exception from my first message.

After that auto reconnect does not work. Calling GoOnline() from code gives the same exception in log.

Have you logged in with someone with permissions to the database? What are your security rules?

Do you get this issue with the quickstart without any changes? (make your database temporarily open and run it on the Lg G3 with the original source code).

My DB rules:
{
"rules": {
".read": "auth == null",
".write": "auth == null",
"Rome": {
".indexOn": ["datetime"]
}
}
}
Let me try to get this error with the quickstart without any changes. Not sure that will be fast because this error very unstable. My app can work some time perfectly till I get this error.

Does this issue this occur with plugin 1.1.2 https://firebase.google.com/support/release-notes/unity#1.1.2 ?

We've extensively tested connection in 1.1.2 and 3.0.0, please check out the latest release https://firebase.google.com/support/release-notes/unity#3.0.0

".read": "auth == null",
".write": "auth == null",
You DB rules states that no authenticated user should access your DB..
Try these rules if you want DB accessible for everyone..
".read": "true",
".write": "true",
