ue4 客户端可以注册，但login总是timeout

[hujuly]

客户端我使用ue4开发，做了简单的登录和注册界面逻辑。

服务器端，注册用户都可以成功，数据库里会有新用户记录。

但是login就会出现日志 pendingLoginMgr::add: username, size=1，接着就显示超时PendingLoginMgr::process:[username] is timeout, currsize=0.请问这是什么原因造成的？我应该如何调试？初学者，求详细点的帮助，谢谢！

在什么情况下会调用PendingLoginMgr？这个还是没搞懂

搞定了，配置问题

你好想问下，是哪个配置的问题

I guess that the Baseapp address or port in the configuration file was incorrect (root/baseapp/externalAddress | externalInterface | externalTcpPorts_min). It was able to connect to Loginapp, but Baseapp's address didn't point anywhere, so the client couldn't connect to Baseapp.

I think is the third case too. I guess that the error "SERVER_ERR_BUSY" is not a cause but a consequence. The user couldn't log in successfully and then click the button "log in" again and again. Thats why there is the error SERVER_ERR_BUSY in the logs. But the point is the why the user coundn't log in by the first time. It needs to find out by the logs what was before the error SERVER_ERR_BUSY.

Is the client the Cocos2D demo?

[ve-i-uj]

If your client is based on the Cocos2D demo You must set the real ip addres in this line (not the localhost or 0.0.0.0) otherwise you can correctly log in only from the PC where the server is running. From the other PC the game will be unreachable.

From the web browser you can request a login window as the request is handled by a web server (Nginx e.g.). But after sending the message "Loginapp::login" KBEngine sends the Baseapp address in the response. And the Baseapp address will be "localhost:20015" because this addres is set in the args.ip. So Baseapp will be unreachable you cannot connect to Baseapp and log in is failed.

So I think that is the reason of your problem.

I think is the second case , but i still haven't figured out what's causing it. It is not the client the Cocos2D demo, and the real ip addres is not localhost.

[ve-i-uj]

Can you reproduce the login issue? If you have the password of the problematic account, you can run [Wireshark] (https://www.wireshark.org/) on the client side and analyze network connections. Use port filters to capture Loginapp and Baseapp network traffic (tcp.port == 20013 or tcp.port == 20015). Try logging in with the problematic account, and then analyze the captured traffic. Captured traffic must have both connections. It is important that the connection to Baseapp exists (tcp.port == 20015).

What the value of root/dbmgr/account_system/accountDefaultFlags in the kbengine.xml file?

[riyueguanghui]

I find out the login issue.

if python script function "onRequestAccountLogin“ throw exception and don't execute the function "KBEngine.accountLoginResponse" ,
the loginName is always exist in reqAccountLogin_requests_. so that it well be always login failure.
