WHY!?!?!?

so, im building a server (aternos) wwith all the mods 10 for me and my friends. so of course i went to the modpacks section of the aternos site and applied it. my client has Neoforge so i can acces it....but it says that it lacks/cant load these mods. is this an aternos problem? if sodo i actually need to put in the missing files myself?

help me out please guys
