Estou tentando configurar um docker swarm entre dois computadores que tenho em casa e um VPS, a configuração é a seguinte:
Manager ip: 192.168.1.132/24
Manager second ip: 192.168.100.1/24 (VPN)
First node ip: 192.168.1.131/24
Second node ip: 192.168.100.2/24 (VPN)
Para criar o enxame que usei docker swarm init --listen-addr 0.0.0.0:2377no gerenciador e para conectar o primeiro nó que usei docker swarm join --token TOKEN 192.168.100.1:2377.
Quando digito docker swarm join --token TOKEN 192.168.100.1:2377no segundo nó, ele se conecta ao gerenciador, mas após um curto período de tempo entra emAbaixoestado.
Alguns serviços replicados estão funcionando, mas não tenho certeza (ou seja, o portainer não mostra o segundo nó corretamente).
Tentei remover a VPN, mas obviamente o resultado foi o mesmo. Não tentei conectar o primeiro nó à VPN, pois acho que isso apenas adicionará sobrecarga à rede. Os logs do docker do segundo nó são os seguintes:

(a saída está truncada para mostrar apenas os problemas de conexão) Estou pensando em mudar para o Kubernetes, mas não sei se isso resolverá efetivamente meu problema.
O que posso fazer? Desde já, obrigado.
