Troubleshooting — JKPanel Server
Structured checks for common JKPanel Server and hosting problems.
Website unavailable
Check DNS resolution, the website configuration, Nginx service status, PHP-FPM status and application logs. An HTTP error code usually provides the first indication of which layer requires investigation.
PHP application error
Confirm the website is using the expected PHP version and that required PHP extensions are installed and enabled. Review the application and PHP-FPM logs before changing the runtime.
Database connection error
Verify the database service is healthy, the database exists, credentials are correct and the application is using the intended host and port.
SSL problem
Confirm the domain resolves to the server, the certificate covers the requested hostname and the certificate chain is valid. Check renewal status if a previously working certificate has expired.
Escalation
When contacting support, include the affected domain, approximate time of the problem, visible error message and the action that triggered it. Do not send passwords or private keys in ordinary support messages.
