Hiya!
I have an issue on my AllTheMods 8 Server.
I am running the modpack version 1.0.11 which is using AEAdditions 4.0.3 of your mod (Forge - AEAdditions-1.19.2-4.0.3.jar).

Every now and then, when I right click a "ME Wireless Transceiver" I tend to get disconnected from my server and see the following screen.

It makes using that block very difficult as it just sometimes works as intended :/
I'd be happy to supply logs, but I can't seem to find any.

I'm getting the same error. I've removed all my existing terminals. Reloaded the game. Taken removed my claim chunks. Nothing works.

I'm playing DW20 1.19.

Could I get any logs of this happening?

Right after right-clicking the ME Wireless Transceiver

[21:43:52] [Netty Client IO #1/WARN] [co.co.Connectivity/]: java.lang.NullPointerException
[21:43:52] [Netty Client IO #1/WARN] [co.co.Connectivity/]: Packet not registered: ClientboundDisconnectPacket
[21:43:52] [Netty Client IO #1/WARN] [co.co.Connectivity/]: io.netty.handler.codec.EncoderException: java.io.IOException: Can't serialize unregistered packet

Any update on this? This just started happening to me on another server.

Not exactly, I've been trying to track down this issue, but it's difficult because the error log doesn't really explain why it's happening.

Here's how I was able to reproduce this myself with some testing after a few players reported it.

1. Create a channel either public or private.
2. Delete channel
3. Save it when there's no other channels that you can see
4. Crash on use

Thanks for the reproduction. I've been able to experience the issue locally and I'll get working on a fix now.

I uploaded a new version to curseforge, can you see if you still have issue now?

Please reopen if you do
