As this mod now requires Fabric Waystones to work (tho from the repo README it seems it's not supposed to work that way?), you can't use it on server-side only anymore. This change allows for use of Waystones (Polymer Port) instead of Fabric Waystones if the mod is installed on server only. You can still use normal Fabric Waystones with this change.
Here's a screenshot of the mod running on client with Fabric Waystones:
