You are running Fabric, and this forum is for Forge. You would probably get more/better help asking for support wherever Fabric support is given.

Please read the FAQ and post logs as described, using a site like https://mclo.gs/

You would probably be better served asking for help where NeoForge support is given.

A lot of the time, modpacks will have server files available for download, double check the curseforge listing and files list for the modpacks you are interested in.

How did you run it? And it should have generated a log or something, which you should post. The log you posted looks like it's from a vanilla server (the minecraft_server jar file)

Do not run minecraft_server.1.7.10.jar You should be running the forge jar.

Cracked launchers are not supported, you must buy the game. Complaining will do nothing. Given the amount of mods out there, and how many ways the game can be played, it's really one of the best deals out there for buying a game. Save up your allowance. *even thought Microsoft sucks.

You need to install Java 21. It tells you how to do it in the FAQ, link is orange banner at top of page that says "Please read..."

I would start with this, looks like one of the mods is missing a dependency

Please read the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/) It will provide more information for figuring out what is going wrong.

Almost, just the java -server -Xmx4G -Xms4G -Dlog4j.configurationFile=log4jformattingfix.xml -jar forge-1.12.2-14.23.5.2860.jar nogui and if that doesn't work, try java --version

Veuillez lire la FAQ (le lien est en haut de la page) et les journaux de publication tels que décrits ici. Cela aidera à déterminer ce qui se passe. Ce sont des forums anglais, j'ai utilisé un traducteur pour essayer de vous aider, j'espère que ça se retrouve bien.

You would probably be better served looking for support where NeoForge support is given, I believe their discord server.

If you copy and paste the java commandline into the terminal, what happens? as in trying to launch it without using the .bat file.

Please read the FAQ and post full logs as described there, it should provide more information that might help determine the issue.

When you make a change and it doesn't work, always post new logs.

Please read the FAQ and post complete logs as described there. It is likely there are other parts that could help explain what is going on.

TileEntity said to use Java 21, not Java 24. If you read the FAQ as directed at the top of the support forum, there is actually a section that tells you which version of Java to use with which version of Minecraft/Forge.

I moved your topic to the support forum, it will likely get more views than the suggestions forum. Please read the FAQ and post logs as described there, it will provide more information.

Looks like probably their discord server: https://fabricmc.net/discuss/

These forums are for Minecraft Forge, not Fabric. You would probably get the best help asking wherever Fabric support is given.

These are the Minecraft Forge forums, and your log is for a Fabric modpack. You would get best results asking for support wherever Fabric support is given.

So I just noticed near the top of the log it says "Launched instance in offline mode", does that mean it is bypassing Minecraft account authentication? If so, that is probably the issue.

Then I would say the issue is most likely prism launcher, if using the vanilla launcher works. Perhaps there is an update for it or something?

Try using the vanilla launcher, if it fails post that log
