Problem Description
Issue
Hello, probably a really stupid question. I have create a Minecraft version with a few mods that i want to host a minecraft server for my friends and me. I have changed the Server type to forge and selected the appropriate Server Version. But when I then Join it mentions that the Mod channel list is mismatched.
When I then transfer the Mod packs to the Mods Folder via SFTP the server wont start anymore. Am I using the wrong files of the Mods on the Server? I cannot find the Server Packs if something like that exists
Reproduction Steps
- Install Minecraft Java
- Configure Server Type to Forge
- Set Forge Version to 40.2.0
- Try to join the server
You need to read the log to know why it can’t start.
If the modpack includes client-only mods, some of those crash when loaded onto the server.
Okay I copied over the once that Game was complaining that were missing.
I saw in the Logs two lines that a version number is not being reported by Mods. Could that be a cause ?
That’s just a version check that they do on startup, it doesn’t limit any functionality if the checks fail
Yeah sorry. Probably just a really stupid mistake I am doing. So for reference these are the mods I would corrently try to run.
And this it what I have moved to the Server.
And as soon as I restart the server then. It doesnt start anymore.
And this it the last error message I found in the server Log:
Error loading class: java/lang/Math (java.lang.IllegalArgumentException: Unsupported class file major version 65)
and Here is the complete Latest.log

Does this help you helping me ? 
All that error says is that you’re missing mods on the server, you need to add the missing mods to the server for things to work. The log also tells you that you’re missing dependencies.
