Current Connection Status
Based on your provided data, your site is experiencing connection timeouts to multiple QUIC.cloud servers:
| IP Address | Server Location | Status | Response Time |

Diagnosing QUIC.cloud Connection Issues
1. Network Routing Issues
The timeouts to multiple QUIC.cloud servers suggest network routing problems:
- Your server may have poor connectivity to certain geographical regions
- There might be firewall restrictions blocking connections
- ISP or datacenter routing issues could be causing the timeouts
2. DNS Resolution Problems
DNS issues can prevent proper connection to QUIC.cloud servers:
- Check if your server can resolve QUIC.cloud domain names
- Verify that DNS servers are responding quickly
- Consider using alternative DNS resolvers
3. Server Configuration
Your server configuration might be causing the timeouts:
- PHP timeout settings may be too low
- cURL might not be properly configured
- Firewall or security modules could be blocking connections
4. QUIC.cloud Server Issues
While less likely, the issue could be on QUIC.cloud's side:
- Specific servers might be experiencing high load
- There could be regional network issues
- Maintenance might be affecting certain nodes
Solutions for QUIC.cloud Connectivity
1. Configure Server for Better Connectivity
Add these settings to your wp-config.php file:
// Increase timeout for external requests
define('WP_HTTP_TIMEOUT', 30);
// Bypass SSL verification if needed
define('WP_HTTP_SSL_VERIFY', false);
// Force IPv4 if IPv6 is causing issues
define('LITESPEED_DEBUG_IPS', 'ipv4');
// Specify preferred QUIC.cloud regions
define('LITESPEED_DEBUG', 'api_region:fr');
2. Optimize DNS Resolution
Improve DNS resolution to prevent timeouts:
// Use reliable DNS servers in your server configuration
// Google DNS: 8.8.8.8, 8.8.4.4
// Cloudflare DNS: 1.1.1.1, 1.0.0.1
// Alternatively, add to your server's resolv.conf
nameserver 8.8.8.8
nameserver 1.1.1.1
3. Adjust PHP and cURL Settings
Increase timeout and connection limits:
// In php.ini or .user.ini:
max_execution_time = 120
default_socket_timeout = 30
// cURL settings
curl.cainfo = "/path/to/cacert.pem"
// In your theme's functions.php
add_filter('http_request_args', function($args, $url) {
if (strpos($url, 'quic.cloud') !== false) {
$args['timeout'] = 30;
}
return $args;
}, 10, 2);
4. Configure LiteSpeed Cache for QUIC.cloud
Optimize LiteSpeed Cache settings for better CDN connectivity:
// In .htaccess or through LiteSpeed Cache plugin
<IfModule Litespeed>
# Force specific QUIC.cloud region
RewriteRule .* - [E=Cache-Control:max-age=3600]
RewriteRule .* - [E=LSQCDN:fr]
</IfModule>
5. Contact Your Hosting Provider
If the issue persists, contact your hosting provider with the following information:
- Provide the specific error messages and timeouts
- Ask them to check firewall rules for QUIC.cloud IPs
- Request they verify network routing to QUIC.cloud servers
- Ask them to check for any DNS resolution issues
Testing QUIC.cloud Connectivity
1. Test Connection to QUIC.cloud Servers
Check connectivity to various QUIC.cloud regions:
2. DNS Resolution Test
Verify that QUIC.cloud domains resolve correctly:
3. Server Configuration Check
Test your server's PHP and cURL configuration:
Preventing Future Connectivity Issues
1. Regular Monitoring
Set up monitoring for QUIC.cloud connectivity:
- Use uptime monitoring services to track CDN availability
- Set up alerts for connection timeouts
- Regularly check LiteSpeed Cache error logs
2. Server Maintenance
Keep your server properly configured:
- Regularly update server software and security patches
- Monitor DNS configuration and resolution times
- Check firewall rules periodically
3. Fallback Strategies
Implement fallbacks for when QUIC.cloud is unavailable:
// In your theme's functions.php
add_filter('litespeed_can_cdn', function($can_cdn) {
// Check if QUIC.cloud is reachable
if (!is_quic_cloud_available()) {
return false; // Fallback to origin server
}
return $can_cdn;
});
function is_quic_cloud_available() {
$test_url = 'https://quic.cloud/';
$response = wp_remote_get($test_url, array('timeout' => 10));
return !is_wp_error($response) && wp_remote_retrieve_response_code($response) === 200;
}
4. Alternative CDN Options
Consider having a backup CDN option:
- Configure Cloudflare as a secondary CDN
- Set up multiple CDN regions for redundancy
- Consider using a different CDN service if issues persist
