C++ Movement Network Warning

I’m using dedicated server in editor and auto connect. When I try to move my character using AddMovementInput, I get the following warning :

LogProperty: Warning: Native NetSerialize StructProperty /Script/Engine.Character:ServerMoveNoBase.InAccel (ScriptStruct /Script/Engine.Vector_NetQuantize10) failed.

My character rotates down and left (not right nor up) and doesn’t move, on all clients. If I don’t use dedicated server, character’s movement work on server but not on clients.

Attacks and jump works and are replicated fine everywhere, so the problem is really movement…

Here’s my code for movement (wich is the base code) :

void ASCharacter::moveForward(const float  Val)
{
	if ((Controller != NULL) && (Val != 0.0f) && (canMove()) 
    {
		// find out which way is forward
		FRotator Rotation = Controller->GetControlRotation();
		// Limit pitch when walking or falling
		if (GetCharacterMovement()->IsMovingOnGround() || GetCharacterMovement()->IsFalling()) 
            {
			Rotation.Pitch = 0.0f;
		}
		// add movement in that direction
		const FVector Direction = FRotationMatrix(Rotation).GetScaledAxis(EAxis::X);
		AddMovementInput(Direction, Val);
	}
}

void ASCharacter::moveRight(const float  Val) 
{
	if ((Controller != NULL) && (Val != 0.0f) && (canMove()) 
    {
		// find out which way is right
		const FRotator Rotation = Controller->GetControlRotation();
		const FVector Direction = FRotationMatrix(Rotation).GetScaledAxis(EAxis::Y);
		// add movement in that direction
		AddMovementInput(Direction, Val);
	}
}

What’s going on, why isn’t the character moving ?

Thanks !

#EDIT :
The warning problem seems to come from here :

#Character.h line 240 - 250

//////////////////////////////////////////////////////////////////////////
// Server RPCs that pass through to CharacterMovement (avoids RPC overhead for components).
// The base RPC function (eg 'ServerMove') is auto-generated for clients to trigger the call to the server function,

Finaly solved it.

I was trying to make instant rotation to my character.

Changing

MovementComponent->MaxAcceleration = 3.40282e+38f;

in my constructor to

MovementComponent->MaxAcceleration = 3.40282e+4f;

Solved it.
