something..

It doesn't, we cant even get into the server it keeps telling me something like failed to synchronize registry data from server.

Long story short, I am trying to play Valhelsia 2 on the CurseForge launcher. I am also playing through a hosting server called, Bisect Hosting. I am trying to add a couple mods to the default game but every time I do it keeps giving me this message. "Skipping config sync, No mods have registered a syncable config". I am clueless on how to fix this, if you could point me in the right direction that'd be great. Thanks.
