Problems Migrating from Plugin to Mod

(Server Hosted on G-Portal, Minecraft 1.21.1, Fabric 0.16.14. DH 2.3.4-b)
(Other Mods: Simple Voice Chat)
Ive switched my server from Paper to Fabric, and while using the Plugin Version of the Serverside support didn't create any problems for me, i just cant get the Mod version to work now.

As soon as a player Joins the console just prints
[DH-PriorityTaskPicker Thread[48]/WARN]: §6Distant Horizons: Insufficient memory detected.§r
followed by the server crashing within seconds.
From what ive understood the way to change the Mods settings is via the /dh config command, but i cant use it because the server just crashes as soon as a player joins. its hard to tell for me how to change values to make it better, as the wiki doesnt state default values or if its in blocks/chunks.
Or if the server just doesnt have enough memory for the mod version, if its way more demanding than the plugin?

If theres any other Info you need let me know, im running dry on my own understanding slowly.

Solution
It doesnt crash anymore on Modrinth (15$/Month package) pregen is running now.
(So dont use Gportal if you do, or use the Plugin version if possible)
