EOFError: Unexpected end of message (on connect())

[DAMcraft]

my client connects to the server but then i get the following error:

(Edit by @joodicator: use triple backticks to properly format a backtrace.)

I have no idea how to fix it, but this part raises the error:

printing byte gives me an empty BYTE-type

[joodicator]

@DAMcraft Is the server you're trying to connect to a public one? Is it a vanilla server, or is it running any mods? Do you know at what point in the connection process this error occurs? (The --dump-packets flag to start.py might be useful.) It's hard to diagnose the problem from the above, but it sounds like the server may be terminating the connection early due to some kind of protocol error or authentication failure.

I have the same problem. It's a public server with some plugins. Here is the output with --dump-packets flag:
