Try to make this a sweet and short as possible.
Forge ver. 12.18.1.2095
Client side when trying to connect to Server: [Netty Client IO #0/INFO] [FML/]: Attempting connection with missing mods [menumobs, jei, inventorytweaks, soundfilters] at SERVER
(All of which are client side mods.)
Server Side when connecting:[user Authenticator #1/INFO]: Disconnecting com.mojang.authlib.GameProfile@507b3700[id=<null>,name=Blacksmithkazuma,properties={},legacy=false] Authentication servers are down. Please try again later, sorry!
[user Authenticator #1/ERROR]: Couldn't verify username because servers are unavailable
Checked Mojangs support site, everything is green.
Why would FML be trying to look for client only mods Server side?
Any help would be great.
