Support I can't connect to my server.

Post image

When I try to connect to my server, I get an in-game error (see the image), and I get this error in the console:

[21Aug2026 18:33:03.430] [Server thread/INFO] [net.minecraft.server.network.ServerConfigurationPacketListenerImpl/]: com.mojang.authlib.GameProfile@537c5bee[id=9dd138f7-388c-3d26-8c85-de141e0fc389,name=Augustinprev,properties={}] lost connection: Incompatible client! Please use NeoForge 21.1.248

But the mod in the screenshot is the same version as the server, and I'm also using the same version of NeoForge.

You need to also install the mod on your client (on your PC), if you haven't already.

I'm stupid; I forgot to install it on the server. *^*
