When I upload a certain amount of data to the Firebase database, I get the following error:

```auto
WebSocket connection to ... failed: Failed to send WebSocket frame.
Firebase Database (4.1.3) INTERNAL ASSERT FAILED: sendRequest call when we re not connected not allowed.

```

Eventually, the data is sent to firebase, but after 20 seconds instead of 1 second.  
The error only seems to happen on iOS.

Anyone have any idea/solution about this issue?
