Issue Pesk interface on port 8443 does not work (ERR_CONNECTION_REFUSED) after nginx purge and reinstall

[Thabet]

Hello,

After executing this command "sudo apt-get remove nginx* --purge", plesk interface does not work anymore on my ip address on port 8443.
I saw in the terminal during the execution of "sudo apt-get remove nginx* --purge" that it was removing alot of components related to plesk itself.
Here's the list of commands I executed:

service apache2 stop
apt-get remove nginx* --purge
apt-get install nginx-common
apt-get install nginx
sudo service nginx restart
service apache2 start

Here's the logs of "service apache2 start":
"
Job for apache2.service failed. See 'systemctl status apache2.service' and 'journalctl -xn' for details.
"

Plesk error:


I don't know what is going on and i'm afraid I broke plesk GUI interface.

Please help me.

Have you tried to fix it with

# plesk repair all

or

# plesk repair installation

?

Unfortunately it didn't work for me.

I made a backup and reverted to a last snapshot.

Unfortunately, the last Plesk update is not perfect either, subdomains are also created with 500.

However, these can be used if you deactivate the proxy in the hosting settings. At least temporarily

I added the following manually. Now the subdomain is also running in proxy mode

Connect to the server using SSH
Change to user root:

• Replace updated version of the file PhysicalHosting.php to /usr/local/psa/admin/plib/Template/Variable/Domain/:
  
  
• wget https://plesk.zendesk.com/hc/article_attachments/4407408199954/PPPM-13232.tgz && tar -xvf PPPM-13232.tgz -C /usr/local/psa/admin/plib/Template/Variable/Domain/
• Rebuild webserver configuration files:
  

plesk sbin httpdmng --reconfigure-all
