Possible Fixes

Yes

Modpack Version

0.2.61

What happened?

When joining a fresh server I have started on a dedicated server, I am getting disconnected randomly. Some players are not able to join, being kicked immediately, while I am sometimes able to be online for a bit before it happens. I have been trying loads of things, java arguments, versions of OpenJava, Ram Amounts, Firewall Disable/rules. I am honestly just at a lost on what to do.

I have a shared hosting plan with bisect and everything works fine for them, so I know its something I am doing wrong. Just not sure what else to try. I don't understand the errors, and it points out a couple mods. Those mods work fine on bisect however so im just not sure. Any help is appreciated.

I've just setup ATM9 today (Version 0.2.61) on a Pebblehost premium server I've been using with little to no issues with an FTB modpack, but with ATM it is also crashing for us with the same error:

java.lang.NullPointerException: Cannot invoke "net.minecraft.client.multiplayer.ClientPacketListener.m_104910_()" because the return value of "net.minecraft.client.Minecraft.m_91403_()" is null

What is odd is the server stops with no reason given, just stops:

06.07 13:57:56 [PebbleHost Loader] Server Stopped
06.07 13:57:56 [PebbleHost Loader] PebbleHost Server Loader Stopping...
06.07 13:57:56 [PebbleHost Loader] Server loader version: v3.0.5 (using configuration version v1.3.8)
06.07 13:57:56 [PebbleHost Loader] PebbleHost Server Loader Stopped.
06.07 13:57:56 [PebbleHost] Server shut down (running)
06.07 13:57:56 [PebbleHost] Server stopped
06.07 13:57:56 [Disconnect] User <> has disconnected, reason: Server shutting down

Yeah I banged my head against the "wall," for 3 days trying to figure this out. Last night I finally decided to switch hosts from one company to one I have used before and liked. Now I have zero issues, unfortunately this doesn't really help anyone who might run into this but I simply couldn't figure out a fix.

My solution was switching dedicated server hosts.
