Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, I did a fresh install of WordPress and Litespeed plugin and was getting the below errors from the Image Optimization when running set tasks So I found an old backup from May 2019 for the site and copied the hash and key, then into the database Then I clicked on (want a fresh start for the site) Reset IAPI Key Destroy All Optimization Data! Then I am getting the same errors as before IAPI Error cURL error 28: Operation timed out after 15005 milliseconds with 0 bytes received Failed to post via WordPress: no auth_key I have also tried on another hsoting provider andd have the same problem The debug log is below 09/07/19 23:13:06.893 [86.0.165.78:62825 1 6bh] ??GET HTTP/1.1 (HTTPS) /wp-admin/admin.php 09/07/19 23:13:06.893
