连接openfire服务器报错 remote-server-error 502怎么解决，怎样开启服务器
After many research on this issue. i found to reason for this as above.
may be your firewall permissions not allow to connect sever.
may your socket setting or ip of server is change.
In my case- i restart my server. and remove firewall setting. Its resolved my problem
so please check your sever socket setting, server ip address and firewall permissions.
and also make sure that server with port 5222 (for device and 9090 for browser ) is always enable.
翻译如下：
1。可能是您的防火墙权限不允许连接断绝。
2。你的socket设置或服务器的IP变化。
我重新启动我的服务器。并删除防火墙设置。它解决了我的问题。
所以，请检查你的socket设置，服务器IP地址和防火墙的权限。
并确保与端口5222（用于设备和9090是用于浏览器）服务器始终启用。
502一般是服务端错误吧，不懂帮顶
