My hestia stopped working all of a sudden, systemctl status hestia command says unit hestia.service could not be found

I have been using this but all of sudden it stops working, please can someone advise what I can do to fix or also to get my mail data stored in the hestiacp as it does not load admin anymore

apt update && apt upgrade -y

update completed but not yet working

‘systemctl status hestia’ says unable to locate package hestia -nginx
‘systemctl restart hestia’ says Failed to restart hestia.service: Unit hestia.service not found
Error: Unable to locate package hestia-nginx
Error: Unable to locate package hestia-php

First, check whether it’s installed or not.

test -d /usr/local/hestia && echo "Exist /usr/local/hestia" || echo "Doesn't exist /usr/local/hestia"
dpkg -l | grep -E 'hestia|nginx'
command -v v-list-sys-info

Check and try to start the panel and Nginx

systemctl status hestia --no-pager
systemctl status nginx --no-pager
systemctl status hestia-nginx --no-pager

Prueba reiniciar hestia si está
systemctl restart hestia

If you’re still not sure whether it’s installed or how it’s installed, you should check the logs to see what they say.

systemctl list-units --type=service | grep -Ei 'hestia|nginx'
journalctl -u hestia -n 100 --no-pager
journalctl -u nginx -n 100 --no-pager

and check to see if APT can find the hestia package, just in case
apt-cache policy hestia hestia-nginx hestia-php

Is there a way I can download my mail data on the server? hestiacp does not work via browser anymore.

pls advise

you alreay search in /home/<ACCOUNT>/mail/<DOMAIN>/ ???
