Repeating Error Code -3, Not Connected using v4.3.3

[djmick]

After initial connection to RTDB using v4.3.3 i'm repeatedly getting "stream timed out, resuming..." followed by "error code: -3, reason: not connected" every 3 seconds. As you'll see in my example code, Firebase.ready() is being called repeatedly.

The library works normally and there is nothing updated that involved this issue.
This is not the library issue unless your network issue which you should use other AP to access the internet or reset your router or change your device or power supply.

[mobizt]

I will check again and update.
