While testing my Legendary Beasts mod by running a "dedicated" server from my computer, I noticed the following issue:

 

Conditions:

Only have a "clientPacketHandlerSpec" defined ->

----client does not receive packets when playing on a dedicated server

---- client does receive packets on an integrated server

 

Have both a "clientPacketHandlerSpec" and "serverPacketHandlerSpec" ->

----client does receive packets on a dedicated server

----client does receive packets on an integrated server

 

 

 

Update forge. it's a known bug with the earlier versions.

Reproducing with Forge 4.0.0.222.

Can you share your @network mod annotation please?

@NetworkMod
(clientSideRequired = true, serverSideRequired = false, clientPacketHandlerSpec = @SidedPacketHandler(channels = CHANNEL,packetHandler = ClientPacketHandler.class),
connectionHandler = ConnectionHandler.class)

That's the Annotation. Like I said, it works fine in SinglePlayer (Integrated Server). Just doesn't work when connecting to a dedicated server, the onPacketData method isn't being called.

You only have a client side packet handler. In a dedicated server, it will never get called. Also update forge for proper behaviour of these..

It doesn't get called on the client when connecting to a dedicated server. However, to fix it I just made a dummy ServerPacketHandler, so it's okay.
