try

systemctl restart hestia
apt-get install --reinstall hestia-nginx
apt-get install --reinstall hestia-php

Is this out of the hestia installation? If yes, you have already something listening on the same port, please use a CLEAN server!

You can also check which service currently using port 8083 on your server (default port for HestiaCP usage) by running comand in shell/ssh:
netstat -tulnp | grep 8083
And after simply uninstall/stop it and running HestiCP setup again (most likely you will proceed with uninstall such one software completely)

The problem can be solved by using the command

sudo apt-get update
sudo apt upgrade
