  4. License Server – Problems and Fixes

As the owner of an active license (see “License Renewals“), you will receive regular plugin updates. In this context, we fix known bugs and introduce new features.

In order for the plugin installed on your website to receive an update, the website or domain must be activated with a license key.

Your personal license key was sent to you by email after you purchased our plugin. Alternatively you can also find on your account page.

The activation itself is done via our license server. In rare cases, there may be problems with the activation of a website, which will be discussed in this article.

Problems, Error Messages and their Causes

cURL error 28: Operation timed out

The cURL error 28 literally means that the website tried to send a request to our license server, but the timeout period specified by the server was reached before a successful result of the request was received.

Problem: It is often the case that hosting providers incorrectly identify the API request as spam and thus block the request at the server level.

cURL error 35: Unknown SSL protocol error in connection

This error occurs if your server cannot establish a HTTPS connection with our license server due to the failed SSL handshake.

Problem: This typically happens when a server runs outdated software and cannot properly connect to our license server (which runs the latest SSL software OpenSSL) via HTTPS.


Possible Solutions

Check your WordPress Security / Firewall Plugin(s)

If you have installed a WordPress Security or Firewall plugin (e.g. Wordfence), check its settings to see if it could block outgoing connections.

If you can't do this yourself, contact the support of the respective plugin provider and ask them to assist you.

Update PHP cURL on your server

Make sure your server has the latest version (see https://curl.haxx.se/docs//releases.html) of the PHP cURL extension installed.

If you can't do this yourself, contact your web hosting provider's support and ask them to assist you.

Update PHP OpenSSL on your server

Make sure your server has the latest version (see https://github.com/openssl/openssl/releases) of the PHP OpenSSL extension installed.

If you can't do this yourself, contact your web hosting provider's support and ask them to assist you.

Whitelist our license servers

Add our license servers to the so-called “whitelist” so that outgoing requests are not blocked. The following information is required:

Domains:

1
https://getaawp.com
1
https://aawp.de

IP addresses:

1
35.205.48.167
1
35.246.190.211

If you can't do this yourself, contact your web hosting provider's support and ask them to assist you.


What happens if you can't activate your website/domain?

In this case, our license server cannot distribute automatic plugin updates to your website.

However, you can also update our plugin manually at any time (as described here) and activate your domain directly via your account page.
