Works Locally, 404 when accessing through Lan network

[GGDRriedel]

The good old problem, I haven't found a solution yet.
I am running through docker, it works on the server itself through accessing it with localhost:8080

However , using the local ip results in a 404

My docker-compose.yml is pretty standard, I changed nothing except exporting te CVAT_HOST variable as it is recommended in the stup instructions.
