Resolved Multiple problems about my server

#1
I know that there are so many of these threads and they all say resolved but my server isn’t working either. I’ve tried changing the name and I was going to roll back but my rollback history has been completely wiped so that wasn’t an option. A lot of the things built on my server have also been wiped and these problems may be because it’s old but I haven’t seen these problems on any other people’s servers and they’ve had their servers on and off since like 2017! So I really need help, please.

Edit: Sorry I wasn’t very specific about the beginning, my server doesn’t turn on after I try to, it just says offline
