1.16.5 modded forge server not working

[kaben015]

Hi,
I wanted to set up a new 1.16.5 server with some mods. I was following the old path: installed forge.jar; installed server.jar; agreed eula and changed server.properties.

But when I ran the forge file it didn't create a mods folder, so I created it myself but that couldn't work either. 

I tried to run a pregenerated world but the process just ignored or skipped the elements that were loaded by the mods.

However, the server is online, I just can't join with my modded client: "Incomplete set of tags recieved from server". (The mods are the same I checked it twice.)

Lastly, I downloaded a premade server modpack folder - because it had a mods folder - and replaced the config files, mods, etc. but nothing changed. Log: https://drive.google.com/file/d/1SXpZtmJjbu6Zou8HMjf_zvo7FigZOtpf/view?usp=sharing

I would be grateful if anyone could help me.
