Modpack server error

[checked01]

Hello, I have been trying to create my first modpack using the technic launcher and have run into an issue I can not seem to fix.

 

My server boots up and gets to the point where you can type commands in it without crashing, and the modpack launches with no issues.

 

However when I try to connect to the server I get the error 

 

The following multiparts are not installed on this client: ConduitEnergy0, ConduitEnergy1, ConduitEnergy2, ConduitFluid0, ConduitFluid1, ConduitItem0, ConduitItem1, ConduitItem3, XU:MagnumTorch, extrautils:fence, extrautils:pipe:Jacket............

clientside.

 

Any help would be much appreciated!

Those indicate that the server has mods which the client does not, or that there is a configuration mismatch between the client and server. Please provide the API URL for your custom modpack.
