getsockopt error when trying to connect to my minecraft server locally

[J-Hahn3156]

I have been trying to setup a minecraft server on an external linux server running ubuntu. When I run the server, I see no errors in the logs, but upon trying to connect to it from a windows computer on the same network, I get the getsockopt error. Now I have checked that the port is published in docker, that the firewall on the linux server is not blocking it, and I am able to ping the computer from my windows environment. I have looked at other post with similar issues and was not able to find a solution that worked for me. I have used the following setup as the compose.yaml:

services:
mc:
image: itzg/minecraft-server:latest
pull_policy: daily
tty: true
stdin_open: true
ports:
- "25565:25565"
environment:
EULA: "TRUE"
volumes:
# attach the relative directory 'data' to the container's /data path
- ./data:/data

It is the default setup that the wiki provides. I have gotten this to work in the past.

Here are the logs:
