Ubuntu Server 20.04 Keeps Shutting Down

I'm fairly new to using ubuntu and brand new to using ubuntu server. I've been working on setting up a physical home server to run some basic tasks. I had the server up and running fine for a couple of days, but then I noticed I was having issues connecting to the server via ssh and then I discovered the server was actually off. I would turn it back on, and it would be fine and then about 45 mins later it would turn off again.

I pulled some of the syslogs to see what was going on here, but I'm fairly inexperienced in this and am having trouble finding out what's going on here. Below are some of the logs before the server shut down.

This server just sits in a closet and nobody is physically touching it. It also shuts down if I turn it on and then just completely leave it alone.

Nu sunt foarte sigur care a fost problema exactă, dar m-am dus și am încercat să elimin orice program care se ocupă de GUI.

Apoi nu am fost și am deschis /etc/default/grub și a adăugat parametrul consoleblank=0 si salvat.

apoi am fugit sudo update-grub și mi-am repornit serverul. L-am conectat la un monitor și nu mai pornește la nicio interfață grafică, iar serverul a fost online acum de peste 24 de ore consecutive fără opriri aleatorii.

Cred că ceea ce se întâmpla a fost că pornește pe un ecran de conectare GUI și, deoarece nimeni nu se conecta direct la server, ar încerca să intre în modul de repaus. Acest server este construit cu părți mai vechi ale computerului, unde am avut probleme cu acest computer vechi care se trezește din modul de repaus.Acest hardware este probabil de vină pentru problemă, dar se pare că cel puțin am remediat-o deocamdată cu procesul de mai sus.
