cURL error 28: Connection timed out after 5000 milliseconds
BackWPup license activation attempt could lead to this error message:
cURL error 28: Connection timed out after 5000 milliseconds
This problem is very rare and usually related to conflicts between your hosting provider and our licensing server. If you experience this error, it will not be possible for you to activate your product license.
We are working on a solution, but currently a fix is not available.
Alternatively, you can just use BackWPup Pro without activating the license. This does not prevent the plugin from working as expected, and when a new version release is available, you can download it in your My Account section and manually update your previous installation.
If you have doubts or need support for the manual update you can always contact our premium support here.
Instead, if you want a refund, consider that this is always granted within 14 days from the first purchase date, as reported in our policy.
