im not sure if this counts as a log or debug log so if it isnt im sorry but this is what comes up when i run the bat file to my forge universal jar file. i have done research and most things say it is with your java type and that it has to be below 9, mine is and its 8 64bit. other people say run from your installer, i honestly dont know what they mean by that but im assuming its the forge universal jar file again, but that itself wont load. i click it and it has a loading symbol over my mouse for half a second and then doesnt even load. i have mods like galacticraft in my mods folder and i dont know if that is affecting it too. Ive tried everything and would really appreciate help. If this isnt the log or debug log please just respond and tell me how so i can give it to you. thanks :)

also my non forge minecraft server jar file runs completley fine its just the forge one that doesnt seem to work.

1.12 is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

    • Start by following the docs to get a workspace setup: https://docs.minecraftforge.net/en/latest/gettingstarted/ Then poke around some of the tutorials, https://www.mcjty.eu/docs/1.20/ used to be the goto, but not sure if there are any updates for regular forge or not, but if you've brushed up on Java, it will be enough to get you started. Poke around the Minecraft and Forge sources to see how things are done. Read the FAQ for information on how to post code/logs when you run into issues. Share as much info on issues you have as possible. Use github to host projects, chances of someone helping are higher when they can actually see all your code and/or build it themselves. And finally, keep it on the forums, don't direct message people with questions, most people do not provide personal support like that. Also keep in mind forums posts are not always immediately answered, if you're looking for a quicker response, you can always try the Minecraft Forge discord server.
    • Hello, I have a Forge Minecraft sever (I host it at g-portal.com) which has always worked fine and I had no problems, but today it doesn't wanna work anymore. Today I started the server and the status said online, but after a few seconds it said this: "Start failed". And then out of nowhere it restarted itself and the same thing happened again and again and now it's in an infinite loop where it just keeps failing and then restarts. Here's the download link for the server logs: https://www.mediafire.com/file/sq30dgoonjevib1/2025-07-06-1.log/file Does anyone know how to fix this? If yes I would really appreciate help. Best wishes, Gabs1107
    • I'm experiencing a critical issue on a dedicated Arch Linux server running the latest Forge for Minecraft 1.20.1. When a player exits a Nether portal (not enters, and not via /tp) or teleports into the End via portal, the server completely freezes for 1–10 minutes. During this time, all commands are unresponsive, and the game world essentially locks up. This is with watchdog disabled. Environment: OS: Arch Linux (latest packages) Java: OpenJDK 17 (up to date) Forge Version: Latest 1.20.1 (tested multiple versions from the past ~3 months) Mods: None (issue occurs on a clean install) Server Type: Proxmox VM with: 4 virtual cores 64 GB RAM (63 GB allocated via -Xmx and -Xms flags) Observed Behavior: Observed Behavior: The server freezes for 1–10 minutes when: Exiting a Nether portal (entering does not trigger the issue) Entering or exiting the End using a portal Teleporting using commands (e.g., /tp) works only for the Nether; teleporting to the End via command also causes a freeze The issue occurs anywhere in the world, not tied to specific coordinates or builds During the freeze: The server becomes completely unresponsive to all commands and player actions No crash reports, no errors, and no warnings are logged CPU usage remains under 50%, and RAM usage stays around 6–14 GB After 1–10 minutes, the server recovers automatically and resumes normal operation
    • Hey man, I just found this section in your code.  Try to do this: { "parent": "minecraft:item/generated", "textures": { "layer0": "testmod:item/alexandrite" } } This means your png should be named alexandrite.png. Hope it helps
