[0.13.0] Unable to connect to headless server

[NoPantsMcDance]

Attempted to join my headless server and I've restarted it and my client multiple times but each time I try to connect I get the "server not responding" prompt and kicked back to the main menu. Server and client logs attached.

I swapped to a new save and it seems to have cleared the issue for now, uploaded the save that was giving me the problem.

I have doubts that the save is responsible, but since it does no longer occur I'll file this under magic as I have hope that with all the changes since 13.0 it got fixed collaterally.
