When updating a premium plugin in WordPress, especially paid ones like Nexter Blocks Pro or Nexter Extension Pro, you may encounter the error message “Invalid License, Update Failed: Download failed. Unauthorized,”
It usually indicates a problem with your license key. Here’s a step-by-step guide to resolve it.
How to Fix the “Invalid License Key” Error
If you’re trying to activate your license key and encounter the “Invalid License Key” error, follow the steps below to troubleshoot and resolve the issue:
1. Ensure You’re Using the Latest Plugin Version
Before proceeding, confirm that you’re running the latest version of the plugin you’re facing the problem with, Nexter Blocks Pro or Nexter Extension Pro.
To check and update your version:
- Visit Nexter Changelog to verify the latest available version.
- If your plugin is outdated and you’re unable to update it due to the license error, you may need to manually update the plugin.
2. Check and Re-Activate Your License Key
Sometimes the error may occur due to a domain mismatch or old license records.
To resolve this:
- Go to your POSIMYTH Store Dashboard.
- Locate your license key under the relevant product.
- Click on the “Manage Site” button (above the license key).
- Deactivate the domain currently using the license (if listed).
- Return to your WordPress site and re-enter the license key to activate it again.
3. Check Your Server-Side Firewall and Security Rules
Sometimes, the license validation or update request from your WordPress site can be blocked by your server’s firewall or security system. If the server firewall is blocking outgoing connections to the licensing updater server, you might see the error when trying to activate the license key.
To fix this:
- Ask your hosting provider or server admin to ensure that outgoing connections (especially to the licensing server) are allowed and not blocked by firewalls, mod_security rules, or other server-side security tools.
If you’re still encountering the error after following the steps above, it could be due to one of the following common reasons:
Reasons
1. There could be a domain mismatch i.e. the website from which you are trying to update the plugin is not connected with the plugin license. This can happen if you first install the plugin on a test site and then move it to the real site using the same license. Even though it might say the license is “Activated,” it’s actually deactivated in this situation.
2. Your plugin license could have expired. If your license has expired and you try to update it, you’ll see this message.
3. You might have entered the wrong license key for the plugin, which will prevent the plugin from updating.
4. Your plugin license might be inactive. If your license key isn’t active and you try to update the plugin, it won’t work.
5. If your WordPress uses an old version of OpenSSL or cURL, the plugin might not update properly because it can’t securely communicate with its server.
Solution
Deactivate and Re-activate License
Deactivate and reactivate the plugin license from your WordPress website; this will fix the domain mismatch issue.
For Nexter Blocks or Nexter Extension plugin, follow the steps –
- From the Dashboard, go to Nexter > Activate PRO.
- Click on the Deactivate button in the Activation Key section.
- Then paste the license key again and click on the Activate button.
