Issue Description:
I am having a issue with Reason 4 and 6 randomly occuring.

ICMP is allowed. Incoming UDP ports 2001, 17777, and 25575 are open. High TCP ports 32768–65535 are also open for established connections (TCP ACK). All outbound traffic is fully allowed.
The server is running in the acemod Docker (debian:bullseye-slim) under Ubuntu 24.04.2 LTS, and the relevant ports are correctly published. However, this error still occurs.

Modlist is added too, I've removed player identities and names from the console for privacy, the console log is available on request.
