我运行了节点，./target/release/node-template --dev --tmp --ws-external --rpc-external 然后按照说明运行了前端。当我尝试从本地网络上的机器连接时，我得到了 "Error Connecting to Substrate { "isTrusted": true }"

我试过 Safari、Firefox 和 Chrome

我该如何解决？

更新：我可以让它在本地运行前端并将substrate-front-end-template/blob/master/src/config/development.json中的PROVIDER_SOCKET设置为远程主机。

它仍然无法与远程机器上的节点和前端一起使用。

解决方案

--unsafe-ws-external --rpc-cors all

到你的参数
