Just to call it out to you, I don't mean to cut in on a Plesk employee here especially being new to the forum... but... it looks like there are a few other issues i noticed that are going to bring the websites and eventually the panel down as well....
Based on the photos I posted back to this thread... I say the only reason you are able to access the Plesk Panel at this moment is because either your ISP or computer still has you DNS Cached... but truth is, the website mentioned isnt showing up because the A records for your Authorative DNS have expired...
This is what i would do first, if i were you...
'sudo plesk repair all -y' - if using ubuntu plesk
'plesk repair all -y' as root user if using centos plesk
if those dns servers do not resolve.. your only asking for hours of headaches....
provided that the dns does not come back up with the repir all command provided... the first thing i am going to recommend doing is fixing you DNS Template file.....
in plesk navigate the following:
Tools & Settings >>
General Settings >>
DNS Template
and here's how my template file looks...
notice how i have the file simplified.... this allows me to worry about minimal Zone records....
but the area causing you problem with the dns is caused by a few different records....
is this file notice the top 4 lines of my file are authorative dns servers that are defined... you only have 2 which is all you really NEED to provide DNS - DEFINETLY DEFINE NS1 AND NS2 it will make things way more simple in the future....if you need help with this one-on-one I am in the Plesk Discord Community and have no problem doing this with you live on a video chat.....
you NS records should be this on the template....
<domain> NS ns1.yerliteknoloji.net
<domain> NS ns2.yerliteknoloji.net
remove the entires on the template for:
ns1.<domain> A <ipv4>
ns2.<domain> A <ipv4>
apply the templatge changes and then mofidy the dns for the domain yerliteknoloji.net to reflect the following:
193.160.214.5 A ns1.yerliteknoloji.net
193.160.214.5 A ns2.yerliteknoloji.net

After those changes have been made in Plesk if you can not get to the client website fee; free to reach out to me and we'll help you get your issues resolved..... but your DNS definetly NEEDS to be working first, because even if you fix the troubled code, your website still will not load.
