Mods Preventing Server From Working

[testoyellowstone]

Hello,

For some context, I've attempted both Java versions 20 & 17 (Currently running Java 20) and made sure that Forge versions are compatible. This is 1.19.2 version of Minecraft btw, running on Forge 43.2.8. I've also noticed that mods only work individually. In other words, multiple mods on the mod folder causes a crash but doing one mod at a time works. Feel free to ask me any other questions to help to resolve the issue. 

This is the report I get when I attempt to run my mods:

A Vanilla Server (without any mods) works totally fine. Adding multiple mods causes the crash on the server. Btw, I've used curseforge to check and see if the mods are compatible by themselves and they run fine without any problems. The problem occurs when I try inputting it in a server. Any help is appreciated!

small error in explanation

[warjort]

Use java 17. Mixin does not support 19 or 20

[testoyellowstone]

I attempted Java 17 again and it still doesn't work.

Java -version in CMD:

java -version
java version "17.0.6" 2023-01-17 LTS
Java(TM) SE Runtime Environment (build 17.0.6+9-LTS-190)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.6+9-LTS-190, mixed mode, sharing)

 

The error I get after using Java 17 again.

I've attempted to use Jarfix as well. I tried running a previous version (18.2) of Minecraft and added a few random popular mods and the crashing is persistent among the servers.

You have a mod trying to load client classes on the server. The error message does not say which mod.

I can see oculus mentioned previously which is a client side mod not needed on the server. You probably have others?

[testoyellowstone]

I got it working!! Thank you so much. I'll share the process that I did for others to see that may be dealing with similar issues as I had to do some research to try fixing the problem before ultimately having to post a forum about it lol.

To those that are dealing with a similar issue:

• ***Ensure that you are using the correct Java Version for the designated Minecraft version. In this case version 1.19.2 of Minecraft which uses Java 17. This can be different depending on the version of Minecraft you are attempting to run a server on. You can also check cmd with the command:       Java -version          to determine if you are running the compatible versions between Java and Minecraft. Jarfix could also potentially help.
  • I think this may have contributed and caused only individual mods to work as opposed to multiple mods in a modpack, but I could be wrong. 
• Even though a modpack works on a launcher, for instance, doesn't mean that it won't crash on a server. ALSO, CHECK CLIENT SIDED MODS and remove them accordingly if necessary to factor out the issues with the server. In my case, I had rubidium, starlight, not enough animations, neat, and oculus (still have to test out which works on the server but remove them to see if the server runs without it first).
• Older versions of Minecraft and newer version mods have different compatibilities (might be obvious to some). For example, 1.16.5 of a mod may be compatible with one server but not with a newer version of MC. The process of starting a server is also only slightly different from older versions to newer ones. 
• If the problem persists or you need help detecting another issue, post it in a support forum like this.
