Quite often, we receive tickets that say nothing more than “My site is unreachable” or “LiteSpeed is down, can you check?” This leads to many messages back-and-forth, because without sufficient information, nobody can tell what happened.
To expedite the troubleshooting process, please review these tips and include any relevant information in your ticket.
An unreachable website is not the same as LiteSpeed being “down.” Is the LiteSpeed process still running? You can run the following command to check: ps -ef | grep litespeed
Is only one domain unreachable? A few domains? All domains on the server? Provide a few domain examples.
Are any errors showing on the browser, such as 503, 403, or 500? Please provide such errors.
Check the server's error_log and find entries that match the above errors. Provide related log entries.
Are you aware of any temporary network issues?
If you use a control panel, can you switch to Apache and see if the error persists?
If it is a WordPress site, and on some of your users are being denied access, it is likely LiteSpeed's WP protection feature, or per-client throttling in effect.
If you provide as much information and as many details as you can when you create your ticket, it will speed up the troubleshooting process, and we may better assist you. Thank you!
