Website & aaPanel Unreachable Until VPS Reboot

aaP_jackievon51

Hi aaPanel team,

I’m having a recurring issue and would appreciate your assistance.

Environment:
VPS provider: Hostinger
VPS specs: 4 vCPU, 16 GB RAM
Panel: aaPanel (latest version)
Website: WordPress
DNS: Cloudflare (proxied mode enabled)

Issue Description:
From time to time, my WordPress website suddenly becomes unreachable. When the issue happens:

Cloudflare shows:
“Web server is down” Host Error;
Browser → Working;
Cloudflare → Working;

aaPanel cannot be accessed either, giving:
connection was unexpectedly closed. ERR_CONNECTION_CLOSED

However, in Hostinger’s dashboard the VPS appears to be running normally (no CPU spikes, no overload alerts, etc.).

The issue can ONLY be resolved by rebooting the VPS.

This problem repeats randomly, which makes the server unreliable.

What could cause both aaPanel and all sites to stop responding simultaneously?

Any recommended steps to diagnose or monitor this kind of intermittent failure?

Any help or suggestions would be greatly appreciated.
Thank you!

Please check if nginx/apache is running?

aaPanel_Kern aaPanel is inaccessible, so I cannot check the status of Nginx/Apache.

Hello,
It is recommended that you check whether the server is running normally? Check whether the server load is normal? Is it possible to use ssh or the server provider's VNC?

aaPanel_Kern The VPS status is normal, and SSH access works without any issues.

Hello, is the problem solved?
If it has not been resolved, you can use the ssh tool to execute the command to check it:
curl -k https://www.aapanel.com/script/aapanel_check.sh | bash
