Dedicated Server Suddenly cut connections

Hi, there :
I’ve encountered an weird issue on our working project :

  • I launched a dedicated server and launched a client to connect it on 127.0.0.1:7800
  • Things goes fine at several minutes since login to the server.
  • But suddenly, the connection is lost without any message.
  • And then , the dedicated server can’t be connected by the client at all. No any message at all.
  • The server is not crashed, and seems work fine its self.
  • The CPU Consumption looks fine ( 0.2% ), so I think its not the infinite loop situation.

Is there any message I’ve lost to find out what this issue is?

Best Regards.

Maybe, very maybe there is any invalidations when RPC on server?
I mean if you need to RPC from client to server you need to validate it first, and as I know once validation will return false client will be kicked from server (but I’am not sure about logs). Maybe somewhere there is same situation?
Have you checked logs? As I can remember in network settings of your project you can enable full network logging level, build project as “development” build and in Saved/Logs in built game there will be logs for network. Actually all logs can be found there.

You could use the Session Frontend → Profiler to capture a session and then step through and see what is going on with the network client or server. This should help point you in the right direction to fixing / finding the problem.

It is what my team has been using to find out how many packets are being sent. What functions are doing what, ect. Great debugging tool for things like this.

It basicly allow you to record a snapshot of time and then step through the stats and see what is going on.
