Server-Side Not Working

The download instructions are unclear. Do I need a hybrid server capable of using both mods and plugins?
I have tried Paper with the server side plugin did not work.
I have tried Fabric with the same mod on client's and server's /mods folder
Solution
I don't know why it did not work before, but after restarting the server it now works.
For anyone with the same problem, make sure:
  1. Fabric's server.jar file (not server.jar from minecraft's download page)
  2. Same Distant Horizons jar in client and server mods/ folder (Downloaded from pinned "Server-side support" on Discord's server "help me" page)
  3. Start/Restart server
"Server has full DH support" is only visible when looking at the sky (F3 Bottom Right Corner)
