🚀 Fix “Request Timeout” & “Service Unavailable” (aaPanel + Apache + PHP 8.x)

💡 Summary

You must adjust three areas to fix timeouts permanently:

① Increase upload limits in PHP
② Raise timeout limits in Apache
③ Extend process / execution time in PHP-FPM

---

✅ Step 1 – Configure PHP

Path:
aaPanel → App Store → PHP 8.x → Setting → Configuration

Set these values:

Then Save → Restart PHP 8.x

💡 These parameters control how large and how long PHP accepts uploads and requests.

---

✅ Step 2 – Configure Apache

Path:
/www/server/panel/vhost/apache/post.domain.com.conf
(Replace post.domain.com with your actual domain.)

Add the following before </VirtualHost>:

Then Save → Restart Apache

💡 If you receive “Invalid command ‘RequestReadTimeout’”,
comment out the module line in httpd.conf:

#LoadModule reqtimeout_module modules/mod_reqtimeout.so


and remove the RequestReadTimeout directive — this disables Apache’s strict request timer completely.

---

✅ Step 3 – Configure PHP-FPM

Path:
/www/server/php/8x/etc/php-fpm.conf
(or /www/server/php/8x/etc/php-fpm.d/www.conf)

Update / confirm the following inside the [www] section:

Then Save → Restart PHP 8.x

💡 These settings let PHP-FPM handle longer executions (up to 10 minutes).

---

✅ Step 4 – Verify & Test

1. Create a file at /www/wwwroot/post.domain.com/info.php:

   <?php phpinfo(); ?>


2. Visit https://post.domain.com/info.php

   • Confirm PHP-FPM is active.

   • Check that upload_max_filesize, post_max_size, and max_execution_time show your new values.

3. Upload an image / video or perform a long request.

✅ You should no longer see:

• “Request Timeout – Server timeout waiting for the HTTP request from the client.”

• “503 Service Unavailable.”

---

🧰 Optional (Recommended for stability)

Add to the bottom of /www/server/apache/conf/httpd.conf:

Then restart Apache:

---

✅ Final Result

Your aaPanel + Apache + PHP 8.x server will now:

• Accept uploads up to 1 GB or more

• Handle long-running PHP scripts (up to 10 minutes)

• Avoid 408 / 503 timeouts permanently
