There might be a datapack that Forge, Minecraft, etc. installed, but I didn't install any.

Still, no (as far as I'm concerned.)

latest.log debug.log.zip

Switching the world worked, but now I get an error saying: java.lang.nullpointerexception. Server debug.log and latest.log are attached.

I'll change to a different world and see if that works

When I removed Optifine on the server, the client still told me the server and the client had the same mod lists?! Thanks, optifine always made the logs so much longer. Logs for server and client with java 8; no optifine on server. And no, no datapacks on server or client (I didn't install any.) server-latest.log server-debug.log client-debug.log client-latest.log

Logs for server with java 8; optifine on server and client. client-latest.log client-debug.log server-debug.log server-latest.log

I was using Java 15; let me check. Edit: Do you want me to provide the debug and latest logs for the server and the client again once I run the server with Java 8? Edit #2: I'll provide the latest and debug server and client logs anyway. Also, should I run Optifine on the server with the java 8?

1. I only have Optifine on the server so that the client and server have the same mod list. 2. The world saves are important, but I can back them up and run the server without them.

Thanks!

My minecraft server and client start up normally with the same forge version, the same mods, and the same wi-fi. When I connect to my server it gives me an error about NBT tags. I have no Idea how to fix this error. Thank you for the help! Latest and Debug logs for both client and server are attached. client-debug.log client-latest.log server-debug.log server-latest.log

I am running my forge server on MacOS Catalina. Will it work correctly if I update to MacOS Big Sur? Thanks!

I checked it out. It was a network error, not related to forge

Thank you again, but then I tried to connect to my server (over the internet) and it did not work. Then I checked the ports and they all said they were open on the router page, but on https://www.yougetsignal.com/tools/open-ports/ it said they were closed. So I tried connecting to my server locally, even on the same machine and it did not work. I'm thoroughly confused. Why did this happen? Thanks for the help!

Thanks! It worked once I manually deleted the files from the folder

So I'll install Java 14 and uninstall java 15. (And how would I uninstall Java 15?)

So... How to fix? Install Java 14?

Running on a MacOs 10.15.7, forge version 1.16.3-34.1.0 I went to start up my server one day to make sure some mods were working, and the server just didn't start up! I tried installing the recommended version also and it failed to launch as well. I have provided a screen recording of me trying to start up my newly installed forge server (link at the bottom) and giving it permissions with chmod (a UNIX command) and still it did not work. I have provided the debug.log, latest.log, and installer.log below and the mentioned screen recording from the newly installed server. It installed perfectly fine. I still have the (not new) other forge server that I had played on before with my friends and when I tried to start it up it did not launch either. All help is much appreciated. Thank you!

I don't have access to the server debug.log currently, I need another few hours. The client debug.log is already on this thread.

I can connect to my server now, but every 30 minutes or so it kicks me and says on the client, "connection reset by peer." Then I rejoin and it changes my game mode to survival, which is okay since I'm op, but I don't want to have to get kicked every once in a while. Can you help me fix this? Thanks!!

I think I know what to do

Is that what messed it up? and what is sha1?

Oh, I just read your spoiler and now I know where to get debug log. So now I get the debug log from the device from which the server and the device which was trying to connect to the server? Client side debug.log: P.S. I don't think it's client side since I recently changed a lot of settings on my server and added mods. debug.log

what is the debug.log? I don't know what this is.

When I try to join my server on the console it says, : [16:47:15] [Server thread/INFO] [ne.mi.co.AdvancementLoadFix/]: Using new advancement loading for net.minecraft.advancements.PlayerAdvancements@64563d01 [16:47:15] [Server thread/INFO] [minecraft/PlayerList]: Arthurmeade12[/192.168.1.254:50237] logged in with entity id 289 at (-224.5, 76.0, 109.5) [16:47:15] [Server thread/INFO] [minecraft/DedicatedServer]: Arthurmeade12 joined the game [16:47:15] [Netty Server IO #1/ERROR] [minecraft/ArgumentTypes]: Could not serialize net.minecraftforge.server.command.ModIdArgument@44cc5710 (class net.minecraftforge.server.command.ModIdArgument) - will not be sent to client!
