Modpack Version:
1.0.6

Describe the bug
After updating the server from 1.0.2 to 1.0.6 both client and server, I can no longer connect to my server as I get "Failed to synchronize registry data from server", I have went through and checked the mods that need to be there and updated forge to the same as the client and of course deleted the libraries folder and placed the new one.

To Reproduce
Update from 1.0.2 to 1.0.6
Expected behavior
For it to work and not throw this error

Additional context
Help me anyway you can.

Decided to delete everything that was included in the new server files and it fixed my problem. Not sure what was causing it.
