Why auto Offline?

The Story Is

I Already Reinstal Server From 1.15.2 To 1.8 And I use Plugins ViaVersion And I Start The Server And WHY Auto Offline Um.. Maybe Lag Or Somethink Please Help I Cant Login to My Server

Info

Server: 1.8 Spigot/Bukkit

I Use 1.15.2 For Connect To My server and Idk Why Auto offline and I Look at Logs Nothing Happens No Red Text WHY

If I Turn On The Server And Before I Enter The Server Is Saving I Don't Know Why It Can Happen, If Anyone Can Help Can Help Pls

I know this problem but, this is not the problem. After the server is online it goes offline offline like someone is controlling it even though I enter when there is a server sound on, I will directly go to the server at 4:10 but when I enter it is already offline and when I see it at aternos.org/server/ It's Saving like Something's in Control
