I’m developing a client-server app. The server side creates a session and the client side joins it.
Until UE 4.16 it worked well, but after the update to UE 4.17 the server side crashes once the client has joined the session.
The thing is it crashes only when using the Oculus subsystem, but still works with Null.
The error is the following:
[2017.09.08-10.24.01:995][ 94]LogWindows: Error: === Critical error: ===
[2017.09.08-10.24.01:995][ 94]LogWindows: Error:
[2017.09.08-10.24.01:996][ 94]LogWindows: Error: Assertion failed: HasReceivedClientPacket() [File:D:\Build\++UE4+Release-4.17+Compile\Sync\Engine\Source\Runtime\Engine\Private\NetConnection.cpp] [Line: 684]
So the problem is the method HasReceivedClientPacket() in the NetConnection class.
This method has been introduced in UE 4.17 (it does not exist in 4.16) and this is what it does (NetConnection.h):
FORCEINLINE bool HasReceivedClientPacket()
{
return !!InternalAck || Driver->ServerConnection != nullptr || InReliable[0] != InitInReliable;
}
May you investigate on this problem?
