Container doesn't start

When running docker compose up, I don't get any further output after "Attaching to snowflake-proxy":

$ docker compose up snowflake-proxy
[+] Running 1/1
 ⠿ Container snowflake-proxy  Created                                                                                                                                                                                                        0.2s
Attaching to snowflake-proxy

I'm running Docker Compose version v2.10.2 and Docker Engine - Community Version: 20.10.18. I've also downloaded the docker-compose.yml and didn't change anything:

$ cat docker-compose.yml 
version: "3.8"

services:
    snowflake-proxy:
        network_mode: host
        image: thetorproject/snowflake-proxy:latest
        container_name: snowflake-proxy
        restart: unless-stopped

I'm running this on a Ubuntu 22.04 LTS LXC. I'm running similar LXCs with more than 20 different docker containers and never experienced an issue like this.
