RLCraft LootTweaker failed custom NetworkCheckHandler

[bennyyy999]

Describe the problem

I used the example docker-compose file and adapted it to the new curseforge stuff, the server is also online, but when I wanna join it gives me this error:

Server Mod rejections: LootTweaker: Failed mod's custom NetworkCheckHandler FMLMod:loottweaker{0.3.1}

In the server mods folder I see LootTweaker-0.3.1+MC1.12.2.jar and my local instance also has 0.3.1 installed.
What is the problem here?

Maybe you need to exclude some mods

https://docker-minecraft-server.readthedocs.io/en/latest/types-and-platforms/mod-platforms/auto-curseforge/#exclude-client-mods

In general though I don't have the bandwidth to support modpack failures, so there's nothing more I can do at this point. Glad to see if anyone else has advice.

Disabling (removing) helped, will see if it affects gameplay in any way.

Will keep this issue open, maybe someone has a better solution.

I’ll convert to a discussion so it can stay open.
