Hi, I am currently hosting a server with a few mods for me and my friends on 1.5.2 using Gregtech 3. Unfortunately nobody can connect to the server because it says that there are mismatching ID’s even tough both the client and server use 1:1 the same configurations on the mods. If anyone can help me and my friends who want to play out it would be greatly appreciated!
Thanks in advance!

Have you tried checking if the IDs are in the configs? Maybe the Configs somehow changed after starting the Server.
And did you make sure that both the GT Version and the Forge Version and the IC2 Version are identical between client and server? I know it sounds stupid and impossible, but I cant really give much advise apart from doublechecking. ^^

Hi Greg,
it was the forge version causing all of the issues.
The issue was 7.8.1.737 in that version of forge it wouldn’t load the Gregtech items.
So i upgraded to 7.8.1.738 and everything is working fine now!!!
So if anyone is having the same problem try upgrading your forge version.
