I have hosted this modpack server for the mech & magic modpack for about a week now and all was good but for some reason now whenever me or my friends try to go on the server our game is frozen until it doesn't respond and we are forced to close minecraft. This happens to both of us so I know it isn't a computer thing and we have both tried going on singleplayer worlds with the modpack and it works perfectly fine.
Any ideas as to why this may be happening?
Thanks.
