使用dotnet run运行RBX Rev网站应用时遇连接拒绝错误求助

问题概述 #

运行RBX Rev网站模块时，持续出现连接被拒绝的错误，核心表现为System.Net.Sockets.SocketException (10061)——目标机器主动拒绝localhost:3185的连接。已尝试关闭防火墙、禁用杀毒软件及代码检查，问题仍未解决。

排查与解决方案 #

• 确认3185端口监听状态
  打开命令提示符，执行以下命令检查端口是否被占用：

  netstat -ano | findstr ":3185"
  

  若无返回结果，说明无程序监听该端口，需检查RBX Rev依赖的后台服务是否未启动，或配置文件中的端口是否配置错误。

• 检查代理服务配置
  查看FrontendProxyMiddleware.cs第109行的代理请求目标地址，确认是否指向localhost:3185的服务配置正确。同时检查RBX Rev的启动脚本或配置文件，确保所有依赖服务已正常启动。

• 验证本地服务可用性
  直接访问http://localhost:3185，若无法响应，说明该端口的服务未启动或启动失败，需查看对应服务的启动日志排查问题。

• 解决端口冲突
  若netstat显示3185被其他进程占用，通过PID结束该进程：

  taskkill /PID [进程ID] /F
  

  之后重新启动RBX Rev相关服务。

• 检查应用权限
  尝试以管理员身份启动RBX Rev，确保程序有足够权限绑定端口和发起网络请求。
