Então, mais algumas notícias:
Boas notícias
Não estou mais recebendo o erro /usr/bin/docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).!
docker run ubuntu não reporta mais erro. @Falco, deveria haver alguma saída que eu deveria estar vendo?
root@forum:/var/discourse# docker run ubuntu
root@forum:/var/discourse#
Então, o que fiz para resolver o erro? Substituí o nameserver (DNS) usado nesta VM pelo serviço Google Public DNS:
echo "nameserver 8.8.8.8" > /etc/resolv.conf
Preciso executar o comando acima toda vez após a VM ser reiniciada (então parece ser apenas temporário), ou receberei os dois erros ao tentar executar qualquer comando ./launcher. Depois disso, apenas um dos erros aparece (Unable to find image 'discourse/base:2.0.20191013-2320' locally), mas o comando parece resolver:
root@forum:/var/discourse# ./launcher start app

Parece que também consigo executar ./launcher rebuild app sem erros. Aqui está a última coisa que a saída do comando mostra (escondendo URLs e endereço MAC):

Ainda estou recebendo o erro 502 Bad Gateway - nginx/1.14.0 (Ubuntu) ao tentar acessar a página.
O que mais poderia ser o problema? Alguma sugestão?
