This is in that log [26Jan2026 20:59:00.322] [main/FATAL] [net.minecraftforge.fml.ModLoader/CORE]: Error during pre-loading phase net.minecraftforge.fml.ModLoadingException: Mod §ebettercombat§r requires §6playeranimator§r §o1 or above§r §7Currently, §6playeranimator§r§7 is §o§nnot installed Sorry for the formatting, it did it on me automatically. I'd be willing to wager that the playeranimator mod won't run on a server, as there are no animations on a server, that's a client thing.

Is that causing an error?

I can't delete this comment.

Hi, I'm using the regular Minecraft java launcher, but I get the same error when I try to join the server via CursedForge. The complete error message reads: Failed to connect to the server You are not logged into your Minecraft account. If you are logged into your Minecraft account, try restarting your Minecraft client. The strange thing is that a few days ago (21. or 22.01.2026) I was able to join the server with Forge, JourneyMap, and Optifine, then I logged off, tried to join again about 10 minutes later, and have been getting this error ever since. Without Forge and the mods, I can join the server without any problems. And I can also join without issues using the LunarClient (Fabric). I never had any problems joining before. I'm using the latest version of Java and playing Minecraft version 1.21.11 (Forge 61.0.6/7/8 doesn't matter, none of them work). The mods are compatible with the Forge version, and the server is also on version 1.21.11 . I've logged in again, restarted my PC, and it doesn't work with other accounts either. I can join a single-player world without any problems. The only thing I haven't tried yet is uninstalling and reinstalling Minecraft. I hope you can help me.

Remove bettercombat

Just removed more client mods. Not sure if its all mods but still crashes. Here is a newer report. https://mclo.gs/CsIWgR2

I take it there is no easy way to find these client only mods? Also is that the only issue so far?

I'm unsure which ones, but you have mods that are trying to load client-only classes (like things related to gui screens, mouse input), and the client does not exist on the server. You will need to identify and remove those mods from the server.

Here is the latest log. https://mclo.gs/pYkBPJA

See if the the log has changed since you did the run.bat, and if so upload that one to the logs site and share the link. Don't use the server.jar, that just runs the vanilla server.

I just ran the run.bat file now it gives an error and won't load. Not sure how to send the cmd here tho. But it runs a bunch of commands and stops saying "press any key" and closes if I press anything.

You need to add the Forge Maven as a plugin management repository in settings.gradle pluginManagement { repositories { gradlePluginPortal() maven { name = 'MinecraftForge' url = 'https://maven.minecraftforge.net/' } } }If are not using the Mod Developer Kit (abbr. MDK) from our Files site, you definitely should. It sounds like you are using a different template, and since we don't make external templates, we can't ensure they will work out of the box.

You need to use the run.bat file for 1.20.1. The server.jar file launches the vanilla Minecraft server. The log you've sent shows a vanilla server running, not a Forge server running.

I am using the "server.jar" file. I do also have a "run.bat" file too. I think I did this right? https://mclo.gs/qN5gIYf

How are you starting the server? If it's a .bat file, show the contents. Also, please post server logs to a site such as https://mclo.gs and post the link here.

I just tried to setup the MDK for 1.21.11 because my mod which runs in 1.21.10 doesn't run in 1.21.11 because it couldn't find the ResourceLocation class. (Minecraft crashed with the error that it couldn't find that class) But after executing the command gradlew init eclipse genEclipseRuns as usual in my commandline, it fails after 1 or 2 seconds with the following error: FAILURE: Build failed with an exception. * Where: Build file 'H:\Laufwerk(E)\Laufwerk(G)\Projekte\Duck Money (Forge 1.21.11)\build.gradle' line: 5 * What went wrong: Plugin [id: 'net.minecraftforge.gradle', version: '[6.0.46,6.2)'] was not found in any of the following sources: - Gradle Core Plugins (plugin is not in 'org.gradle' namespace) - Included Builds (No included builds contain this plugin) - Plugin Repositories (could not resolve plugin artifact 'net.minecraftforge.gradle:net.minecraftforge.gradle.gradle.plugin:[6.0.46,6.2)') Searched in the following repositories: Gradle Central Plugin Repository * Try: > Run with --stacktrace option to get the stack trace. > Run with --info or --debug option to get more log output. > Run with --scan to get full insights. > Get more help at https://help.gradle.org. BUILD FAILED in 4s Does somebody know what I may miss here?

I'm trying to start a modded forge server to play with friends, installed the server client, did everything with the minecraft .jar file to create the server files, created a mods folder and placed the mod in it. The mods work and run just fine in singleplayer but do not work within the server. The server runs perfectly but only client-side mods work. This is a custom mod pack that has been tested and works just fine in single player. I did try the server WITHOUT client side mods (or least removed the known client mods). Here is the download code. a0TWt630 Minecraft Version: 1.20.1 Forge Version: 47.4.10 openjdk version: 21.0.9

Report it to the creator - I think it is some kind of bug with the mod - or maybe a conflict with models from another mod https://github.com/Lightman314/LightmansCurrency/issues Caused by: java.lang.NullPointerException at java.util.Objects.requireNonNull:unknown at io.github.lightman314.lightmanscurrency.api.variants.VariantProvider.get:L79

I've been running a rather large modpack in 1.20.1 for some time now without issue. This mod includes Create, as well as a number of mods dependent on Create, including Valkyrien Skies. Up until recently, VS was only compatible with older versions of Create, however a number of recent updates to VS has made it compatible with the latest versions of Create, allowing me to update it and it's dependents. Unfortunately, this has resulted in a rending overlay error that causes the game's text to become unreadable, as well as causing worlds to crash immediately on startup. I've tried removing potential problem mods like Embeddium & Sinytra Connector, but to no avail. Any help would be greatly appreciated. Crash logs with Embeddium & Sinytra Crash logs without them.

Make sure you have Minecraft Java Edition. Download the forge installer for the version you want from https://files.minecraftforge.net/. (Optional)Use the Minecraft launcher to create a new installation for this version, using a separate game directory, so you do not corrupt existing saves with mod data, or vice versa. Many players find it easier using a launcher such as Curseforge or AT Launcher to make installing mods and modpacks easier. If you do so, these launchers will install MinecraftForge for you.

I want tp instal Forge
