  • Today I decided to create a server using the FTB Ultimate modpack, so I installed it through my server and I installed the modpack through Twitch. I got the modpack itself working after playing on a single player world for a few minutes, but when I click add server in the multiplayer section and put in the address, it says can't connect to server. Am I missing something? Do the versions have to perfectly match?
