Server operating system version

Debian 12

Plesk version and microupdate number

Hello,

recently i head to this link: https://mywebsite:8443/admin/update/product/
and i get this error page:


when i go to Open the repair kit i didn't find any thing abnormal,
Disk space is 80% free, services are running normally, i even don't have problem with my website
tried to restart services and the server its self and the same

so what else i could try ?

What happen when you try going to https://yoursite:8447 ?

What happens if you try running the follow command in a SSH session:

plesk installer install-panel-updates

do you mean when open https://yoursite:8443 not 8447 ?
it opens plesk dashboard

 

[scsa20]

do you mean when open https://yoursite:8443 not 8447 ?

Port 8447 goes directly to the plesk installer/update, thus why I'm asking what happens when you go to 8447.

 

[MISHO0o]

It stuck on loading page but not opening anything

 

[scsa20]

Looks like there might be issues with the packages, you might be able to try to reinstall Plesk by doing the following:

wget https://autoinstall.plesk.com/plesk-installer
chmod +x plesk-installer
sh ./plesk-installer

Follow the prompts to reinstall/upgrade.

 

[MISHO0o]

is this will effect on current running websites ?

 

[scsa20]

Most updates will make changes to Nginix and Apache causing the service to restart so ye it can effect the web sites, why you should always make sure you have a backup, a snapshot, etc. and do it during a maintenance window.
