Hi everybody. I have a problem that I can't find a solution to anywhere. When the server starts, the "Shutdown handler: cleanup." pops up.
I installed ubuntu server 22.04 lts on linux via steamcmd. AMD-FX-6100 processor and 16 GB RAM.
The launch goes through the .sh file: ./RustDedicated -batchmode +server.ip *.*.*.* +server.port 28015 +server.tickrate 10 +server.hostname "Your Server Name" +server.identity "your_server_identity" +server.seed 10469777 +server.maxplayers 200 +server.worldsize 3500 +server.saveinterval 600 +rcon.ip *.*.*.* +rcon.port 28016 +rcon.password "123456" -logfile "logfile.log"

Open ports via iptables:
sudo iptables -P INPUT ACCEPT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -F
sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 28016 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 28015 -j ACCEPT
sudo iptables -A INPUT -i lo -j ACCEPT
sudo iptables -A INPUT -j DROP
sudo netfilter-persistent save

Open ports on the router: 28015 UDP

The full server startup cycle recorded in the log file: https://disk.yandex.ru/d/2flCd87BePqFOg

Help please :)
