Server pack mods different to client mods?

[frank root]

Hi, sorry if this has been asked before, I did have a look but couldn't see anything similar.

I've downloaded RAD2-Serverpack-1.6 from cursed forge, followed the server set up steps, went to log in and got 'incompatible fml modded server'.

I checked the mods downloaded for the client and it's 270+ but in the server pack it is only 252.

My questions are -
Have I downloaded the right/ most up to date server pack?
Is there are list anywhere of all the mods I need to remove from the client, or do I just need to manually go through them and make a list for my friends to also remove/ can I add the missing mods to the server pack or will that break things?

Thanks!

@frank root that warning is inaccurate ilom forge due to it not checking for client side mods

Client will have client side mods that wont be on the server

Oh so it should be fine? Let me try I thought it wouldn't let me log in but I'll just double check

It even says this info may be inaccurate due to blah blah
