How to Fix LiteSpeed Cache Domain Key Errors: Step-by-Step Solutions

If you’re having trouble generating a domain key for LiteSpeed Cache, here are some common solutions and troubleshooting steps:

1. Check LiteSpeed Server Setup

• Ensure your server is using LiteSpeed. LiteSpeed Cache requires a LiteSpeed or OpenLiteSpeed server to function correctly. The domain key won’t be generated if you’re not on a LiteSpeed server.
• Confirm LSCache is Enabled: Ensure that LSCache is enabled in your server configuration. You can ask your hosting provider to verify this.

2. Update LiteSpeed Cache Plugin

• Make sure you’re using the latest version of the LiteSpeed Cache plugin for WordPress. An outdated version might cause issues when generating a domain key.
• Go to Dashboard > Plugins > Installed Plugins, and check if any updates are available for LiteSpeed Cache. If so, update the plugin.

3. Network Connectivity

• Check your server’s internet connection: Your server needs to be able to communicate with LiteSpeed’s API to generate a domain key. Ensure there’s no firewall blocking outgoing requests from your server.
• Firewall Settings: Make sure your server’s firewall or security settings aren’t blocking outgoing connections to LiteSpeed’s servers. You may need to whitelist quic.cloud.

4. Manually Request a Domain Key

• If the automatic process fails, you can manually request a domain key.
• In the LiteSpeed Cache plugin:
  1. Go to LiteSpeed Cache > General.
  2. Look for the Request Domain Key button and click it.
  3. Wait for the plugin to communicate with the LiteSpeed server.

5. Verify Correct DNS Setup

• Ensure that your domain’s DNS is properly set up and pointing to your server. An incorrect DNS configuration might cause issues in communicating with LiteSpeed servers.

6. Check for Conflicting Plugins

• Sometimes other plugins might conflict with LiteSpeed Cache. Temporarily disable other caching or security plugins to see if this resolves the issue.

7. Review Server Logs

• Check the server logs (LiteSpeed logs, or web server error logs) for any errors or messages related to LiteSpeed Cache or the domain key generation process.

8. Reach Out to Hosting Provider or LiteSpeed Support

• If you’re still unable to generate the key, your hosting provider may be able to help resolve any server-level issues. You can also contact LiteSpeed support with detailed information on the error you’re facing.
