当我尝试将远程客户端连接到我的服务器时出现此异常。我的服务器运行 RMI 服务器正常，并且没有安装防火墙。如何解决该问题？
最佳答案
检查所有网络适配器，有时 VM 网络适配器会以这种方式进行干扰。
您当前的 localhost 或 127.0.0.1 不再指您的主机名或当前机器，这将导致连接被拒绝的问题。我的一般建议是:
1.To check or disable unwanted VM or Network Adapters
2.Ping 127.0.0.1
3.Disable Firewall and Test if all the above doesn't work
4.Add security Manager with a policy file on you server if you haven't done that.
