Problemas con nginx-proxy y letsencrypt

[SebastianRiquelmeM]

Espero puedan ayudarme, la verdad no tengo idea de que está fallando. Tampoco me manejo tanto con escribir issues en github, espero hacerlo bien.

Contexto en el que estoy trabajando

Estoy usando un VPS en oracle cloud.
Arquitectura: ARM
Dominio: Compré sebastianriquelme.cl en nic.cl
DNS: nic no proporciona un DNS según entendí, por lo cual configuré cloudflare como DNS. Tengo desactivado el proxy en cloudflare y el forzar HTTPS (creo), esperando que no interfiera con letsencrypt.
Tengo los puertos 80 y 443 abiertos y funcionando, detuve los procesos anteriores que usaban estos puertos.

Descripción del problema

Estoy usando el siguiente docker-compose.yml:

version: "3"

services:
    nginx-proxy:
        image: budry/jwilder-nginx-proxy-arm
        restart: always
        ports:
            - "80:80"
            - "443:443"
        volumes:
            - /var/run/docker.sock:/tmp/docker.sock:ro
            - /home/ubuntu/nginx_docker/config/certs:/etc/nginx/certs:ro
            - /home/ubuntu/nginx_docker/config/confd:/etc/nginx/conf.d
            - /home/ubuntu/nginx_docker/config/vhostd:/etc/nginx/vhost.d
            - /home/ubuntu/nginx_docker/config/html:/usr/share/nginx/html
            - /home/ubuntu/nginx_docker/config/acme:/etc/acme.sh
        labels:
            - com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy

    letsencrypt:
        image: jrcs/letsencrypt-nginx-proxy-companion:stable
        restart: always
        volumes:
            - /home/ubuntu/nginx_docker/config/certs:/etc/nginx/certs:rw
            - /home/ubuntu/nginx_docker/config/confd:/etc/nginx/conf.d
            - /home/ubuntu/nginx_docker/config/vhostd:/etc/nginx/vhost.d
            - /home/ubuntu/nginx_docker/config/html:/usr/share/nginx/html
            - /var/run/docker.sock:/var/run/docker.sock:ro
            - /home/ubuntu/nginx_docker/config/acme:/etc/acme.sh

    test:
        image: nginx
        restart: always
        expose:
            - "80"
        volumes:
            - /home/ubuntu/nginx_docker/subdominios/test:/usr/share/nginx/html:ro
        environment:
            - VIRTUAL_HOST=test.sebastianriquelme.cl
