So my server keeps randomly going offline an every time I read the logs the only last thing it says is vault is checking for updates and there's no errors so I only assume vault is the problem im on 1.19.3 please help

This might just be a coincidence. Have you tried running your server without Vault to see if the problem continues?

I have not mainly cause it happens at random sometimes the server can take 15 hours to shutdown other times it happens in just an hour of being up

You should post the server log file. otherwise ists nearly impossible to help.
