Title: Image Optimization cURL error Last modified: May 31, 2018 --- # Image Optimization cURL error * Resolved [majama](https://wordpress.org/support/users/majama/) * (@majama) * [8 years ago](https://wordpress.org/support/topic/image-optimization-curl-error/) * ERRORS: IAPI Error cURL error 28: Operation timed out after 15000 milliseconds with 0 bytes received Failed to push to LiteSpeed IAPI server: “no auth_key” * BACKGROUND: We recently migrated our site to a new VPS. Image optimization was working fine on the old server; however, I’ve been running into some issues with the new server. I already updated the IAPI key. Any suggestions on how I may solve this problem? * SITE LINK: [https://SquarzPies.com](https://SquarzPies.com) * REPORT: TXQGBZCB * DEBUG LOG: 05/31/18 00:07:36.385 [34.198.229.186:41844 1 bOv] POST HTTP/1.1 / 05/31/18 00:07:36.385 [34.198.229.186:41844 1 bOv] Query String: litespeed_callback =1 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv] [IAPI] __callback hash check Moy6TbfV2aeaEYvg: passed 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv] [Router] LSCWP_CTRL: sapi_passive_callback 05/31/18 00:07:36.982 [34.198.229.186: 41844 1 bOv] [Router] LSCWP_CTRL verified: ‘sapi_passive_callback’ 05/31/18 00: 07:36.982 [34.198.229.186:41844 1 bOv] [Router] parsed type: request_callback 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv] [IAPI] __callback request hash: Moy6TbfV2aeaEYvg 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv] [Ctrl] not cacheable before ctrl finalize 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv] [Router] get_uid: 0 05/31/18 00:07:36.982 [34.198.229.186:41844 1 bOv][ Router] get_role: 05/31/18 00:07:36.983 [34.198.229.186:41844 1 bOv] [Router] role: guest 05/31/18 00:07:36.983 [34.198.229.186:41844 1 bOv] [Vary] role id: failed, guest 05/31/18 00:07:36.983 [34.198.229.186:41844 1 bOv] X-LiteSpeed- Cache-Control: no-cache 05/31/18 00:07:36.984 [34.198.229.186:41844 1 bOv] GUI init 05/31/18 00:07:36.984 [34.198.229.186:41844 1 bOv] [Optm] bypass: Not frontend HTML type 05/31/18 00:07:36.984 [34.198.229.186:41844 1 bOv] End response * =============================================== 05/31/18 00:07:48.679 [98.191.186.108: 59482 1 b3i] [IAPI] failed to post: cURL error 28: Operation timed out after 15000 milliseconds with 0 bytes received 05/31/18 00:07:48.679 [98.191.186.108: 59482 1 b3i] [IAPI] request key failed: — ‘cURL error 28: Operation timed out after 15000 milliseconds with 0 bytes received’ 05/31/18 00:07:48.703 [98.191.186.108: 59482 1 b3i] [IAPI] posting to : [https://wp.api.litespeedtech.com/request_optimize](https://wp.api.litespeedtech.com/request_optimize) 05/31/18 00:07:49.302 [98.191.186.108:59482 1 b3i] [IAPI] failed to decode post json: “no auth_key” 05/31/18 00:07:49.302 [98.191.186.108:59482 1 b3i] [Img_Optm] Failed to post to LiteSpeed IAPI server — ‘”no auth_key”‘ 05/31/18 00:07:49.306[ 98.191.186.108:59482 1 b3i] [Ctrl] not cacheable before ctrl finalize 05/31/18 00:07:49.306 [98.191.186.108:59482 1 b3i] [Router] get_uid: 1 05/31/18 00:07: 49.306 [98.191.186.108:59482 1 b3i] [Router] get_role: administrator 05/31/18 00:07:49.307 [98.191.186.108:59482 1 b3i] X-LiteSpeed-Cache-Control: no-cache 05/31/18 00:07:49.307 [98.191.186.108:59482 1 b3i] [Optm] bypass: Not frontend HTML type 05/31/18 00:07:49.307 [98.191.186.108:59482 1 b3i] End response - This topic was modified 8 years ago by [majama](https://wordpress.org/support/users/majama/).
