Not getting any logs on console or client side,
Running a Fabric server (latest version) through a docker container on a Debian 12 VM
Attempting to use the Tekxit 4 modpack, on MC version 1.19.2
All mods should be the same between client and server, only difference would be that

doesn't look like the issue was really solved in that post from what I can see, they just moved their mods out and back into a folder?

lavaking46•8/26/24, 3:39 AM

They said that after doing that + adding other serverside mods the issue was solved

garamondOP•8/26/24, 3:50 AM

why would my mods be out of sync between client and server if both are downloaded from the same source and have the same modpack version

I've seen that thread as well, disabling the two mods it talks about doesn't seem to change anything

lavaking46•8/26/24, 3:51 AM

Just to be sure, when you say you aren't getting any logs, did you also check the files created after the fact? sometimes things get missed.

Custom Modpack server help

So me and some friends have a custom modpack that we play on and it had been working just fine, however recently it broke and it keeps crashing every time it loads up. I have included a link for anyone interested in helping me but be warned the server file is very large even after being compresse...

lavaking46•8/26/24, 3:54 AM

Also did you make sure no client side mods are on the server?

garamondOP•8/26/24, 3:55 AM

I downloaded the server download so if that held client side mods then yes but I would be surprised

garamondOP•8/26/24, 3:56 AM

I didn't check world files for corruption as I'm not sure how to check that, any other generated files that I should check?

lavaking46•8/26/24, 3:57 AM

possibly configs, mostly just the world files I think. An easy way to check if to load the world in singleplayer and see if anything weird occurs or if your client log has anything extra.

garamondOP•8/26/24, 3:57 AM

I'll check that out

lavaking46•8/26/24, 3:58 AM

Beyond what I've said I'm not really sure at this point. I'm mostly just following the trail of forums from searching the error. I don't know how much more help I can be.

garamondOP•8/26/24, 3:58 AM

Something else to note could be that my data folder has all the mods buried

lavaking46•8/26/24, 3:59 AM

Thats also something to check

lavaking46•8/26/24, 3:59 AM

probably

garamondOP•8/26/24, 3:59 AM

yeah I get that, I've been down this rabbit hole for a bit now so i've seen most of these forum posts

garamondOP•8/26/24, 3:59 AM

should i just try moving all the mods to the top level?

lavaking46•8/26/24, 3:59 AM

maybe

garamondOP•8/26/24, 3:59 AM

hell worth a shot

lavaking46•8/26/24, 3:59 AM

idk if it will make a difference but the likely worst case scenario is that it gives you a fixable error

garamondOP•8/26/24, 4:00 AM

I'm wondering too if its an issue with docker not launching the right jar file

garamondOP•8/26/24, 4:07 AM

okay we're getting somewhere, moved all the mods to the top level folder

garamondOP•8/26/24, 4:09 AM

okay so i just reenabled and
