Docker/Pterodactyl Issues

Docker containers may have Internet connection problems. Here's how to solve them

Open the /etc/pterodactyl/config.yml file and change the "network_mtu" to 1370

Fixed Wings config

Now, open the /lib/systemd/system/docker.service file and add at the end of the ExecStart line --mtu=1370

It should look something like this

ExecStart=/usr/sbin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock $DOCKER_OPTS --mtu=1370

Now reload your docker configuration

systemctl daemon-reload

Stop Docker and wings

systemctl stop wings docker

Delete the docker network interface

ip link delete docker0

Restart Docker

systemctl start docker

Clear network interface and images

docker system prune

Type "y"

Clear the wings database

rm /var/lib/pterodactyl/wings.db

And now restart wings

systemctl start wings
