Difference between socket- and port-based connection to outer NGINX?

wanghaisheng · Dezembro 24, 2019, 4:54pm

@tophee @Lutz por favor, deem-me algumas dicas, obrigado
Tenho 3 multisites em execução, cada um com HTTPS desabilitado e um nginx rodando sobre o host. O nginx.conf é assim. A URL retorna erro 522.

events {
    worker_connections 1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    init_by_lua_block {
        -- Defina uma função para determinar quais domínios SNI devem ser
        -- tratados automaticamente e para registrar novos certificados. O padrão é não permitir
        -- nenhum domínio, então isso deve ser configurado.
        function allow_domain(domain)
            if domain:find("antivte.com$") then
                return true
            end
            return false
        end

        -- Inicializa a instância do servidor de certificados de backend.
        cert_server = (require "resty.ssl-cert-server").new({
            backend = '127.0.0.1:8999',
            allow_domain = allow_domain
        })
    }

E este aqui está funcionando corretamente:
