aaPanel Freezes at 90% When Applying Let's Encrypt SSL, Requires Server Restart

alreza

Dear aaPanel Support Team,

I am experiencing a critical issue while trying to apply a Let's Encrypt SSL certificate for my subdomain through aaPanel. The process freezes at 90% and completely locks up the panel, forcing me to perform a hard server restart to regain access.

Here’s what happens step-by-step:

I go to the SSL section and select Let's Encrypt.

I choose the domain (qurani.vazeeiat.ir), select DNS verification, and click Apply.

The progress reaches about 90%, then the entire aaPanel interface becomes unresponsive.

The panel does not recover even after waiting for 30 minutes.

Refreshing the page does not help—the panel fails to load entirely.

The only way to restore functionality is to perform a hardware restart of the server.

Important notes about my setup:

The subdomain (qurani.vazeeiat.ir) is configured in Cloudflare with an A record pointing directly to the server IP (without proxy).

I am not using CDN or redirects that might interfere with file-based verification.

The domain resolution is properly set and confirmed.

This issue is severely impacting my server management and website security. I urgently need assistance to resolve this so I can enable SSL without crashing the panel.

Could the aaPanel team please investigate this? It appears to be a significant bug in the SSL application process. If logs or additional information are needed, I’m happy to provide them.

Thank you for your attention and support.

Best regards,

Hello,
Thanks for your feedback,
Just this once? Currently we have not reproduced this issue
Are you using Nginx or multi-server (nginx+apache+openlitespeed)?
How many websites exist?
You can try to apply for SSL again, and use the ssh tool to execute the topcommand to check whether the server load is normal?

Dear aaPanel Support Team,

Thank you for your prompt response and guidance.

To answer your questions clearly and provide context:

Frequency & Scope: This issue occurs every single time I attempt to issue a new Let's Encrypt SSL certificate for a new domain or subdomain. The process consistently freezes at approximately 90% and requires a hard server restart. However, it's important to note that renewals for existing certificates are working perfectly via an automated script I have in place. The problem is isolated to new certificate issuance.

Web Server Environment: In the "Website" section of my aaPanel, I am using Apache 2.4 as my standalone web server. I am not using the multi-server (Nginx + Apache) or OpenLiteSpeed setup.

Server Load & Resources: As requested, I attempted the SSL application again while monitoring server resources via top in SSH. The attached screenshot shows the system state just before the panel froze. The server load and resource usage (CPU, RAM) were well within normal and optimal limits—there was no abnormal spike or consumption that would explain a complete system hang.

Summary: The problem is a repeatable, critical bug that completely locks the panel during the initial issuance of a new SSL certificate. The server environment (Apache 2.4) is stable, and resources are not the bottleneck, as evidenced by the monitoring data.

I urgently need your help to diagnose and resolve this, as it blocks the deployment of any new secured service on my server. Please let me know if you require specific log files from the panel (e.g., /www/wwwlogs/panel) or from Apache to investigate further.

Thank you for your dedicated support.
