No supported authentication methods?

How do I resolve this error?
Disconnected: No supported authentication methods available

Here's the script I'm running: https://pastebin.com/pbGsdmhw

And here's the log: https://pastebin.com/9kBrhykc

I have no idea what the error means or how to fix it.

Please try it with 4.3.5. If nothing else, it would show list of authentication methods your server supports in the error message.
