Hello,
I've been having this issue when players connect, resulting in them getting kicked eventually, sometimes not allowing them to reconnect.
All ports have been opened (UDP/TCP)28015-28019
Rust_server.exe allowed through firewall (Inbound/outbound)

I've made sure all configuration is correct, this is the only error I get.

If anyone with an understanding can help in any way I'd be extremely greatful!
Thank you.

Probs not so relative now, apologies for the late answer. This has always been a known bug through the years, usually happened when the server was running for a very long time and something broke. Maybe the next reporter should attach all their logs and we can maybe figure this out. But legacy has a shitty code base for sure.
