([localhost:8048]) tried: java.net.ConnectException: Connection refused: connect

当出现"([localhost:8048]) tried: java.net.ConnectException: Connection refused: connect"错误时，说明客户端试图连接到指定的地址和端口，但是连接被拒绝了。有几种可能的原因导致这个错误出现。一种可能是目标地址上没有正在监听的程序，即没有程序在指定的TCP端口上进行监听。另一种可能是防火墙阻止了TCP连接请求。

通过将URL中的本地IP地址更改为node.js中的监听IP地址"127.0.0.1"，您可能会解决这个问题。这个IP地址是本地回环地址，表示连接到本机。

请注意，上述内容是根据提供的引用内容进行的推测。如果您需要更具体的解决方法，请提供更多的上下文信息或相关代码。
