General Questions regarding use of Forge and Versions

[Nifoyg]

I have recently started a server that will be used by myself and friends.  My computers MC java version is 1.16.5 like everyone.  However the versions of some mods I downloaded off the forge site are all version 1.16.4.  I do get a versioning issue when I connect to my MC server, I assume this is the issue.  Do I need to wait until these 1.16.4 mods need to get updated to 1.16.5 before I can use them?  (or can they be used as is?)  Is there a location in the .jar of each mod where I can change the version of these mods, etc?

 

One other issue I do not understand yet is why is my system prompting me to put my mods under my 'user minecraft' area? (C:\Users\Phil\AppData\Roaming\.minecraft\mods)  It would seem they should go under the server's mod directory (C:\MC\forge\server1.16.5\mods).

Most mods need to be installed on the client AND the server.

I hope by "forge site" you mean CurseForge (Note: no affiliation between us and them)

1.16.4 mods should "just work" on 1.16.5 unless they did something the wrong way that now won't work
