Can't access Panel ERR_CONNECTION_TIMED_OUT

I’m suddenly unable to access my Hestia panel: the sites are working, but I can’t log in to the panel: ERR_CONNECTION_TIMED_OUT. It was working perfectly since February 25, 2025. I’ve already tried: “sudo reboot”, “sudo systemctl restart hestia”, restarting the server, and sudo systemctl status hestia says that the service is active and running. Some help?

Maybe you have blocked yourself:

v-list-firewall-ban | grep HESTIA

If you don’t see your IP in the list, show the output of these commands:

systemctl status hestia --no-pager -l
netstat -tnap | grep nginx
iptables -S

firewall clean

root@panel:~# systemctl status hestia --no-pager -l

Accesing your site directly it works fine:

You have a redirection loop problem. Cloudflare doesn’t support port 8083, so you should change it to something like 2083.

v-change-sys-port 2083

Since when? It’s always worked this way. Is something new?

No, Cloudflare never supported port 8083. I don’t really know how did you configure it…

Thank you Sahsanu, you’re a master genius.
