Says that the mod exists when I suggest it, doesn't come up when searching for it.

Wanted to add mods such as Pam's Harvestcraft, Upgraded Netherite and RevampedWolf but whenever I search under mods they don't come up? I then tried suggesting these mods and Aternos says it is already available. Am I doing something wrong? I never added mods on Aternos before.

Ohhhh okay, new to modding, apperently I was using Fabric when they are Forge mods.
