Title: ImageOptimization: Failed to fetch Last modified: May 5, 2020 --- # ImageOptimization: Failed to fetch * Resolved [mazze5](https://wordpress.org/support/users/mazze5/) * (@mazze5) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/) * Hi, * I am using LiteSpeedCache the first time. Version v3.0.8.5 and since yesterday 3.0.8.6. * From Request to Pull it seems to be really slow. But maybe thats normal? * I could optimized a few images(11), but now I get the following error in wordpress: Images failed to fetch * And on quic.cloud I see something like that: * ``` Error: Fetched md5 mismatch: [latest] d41d8cd98f00b204e9800998ecf8427e [ori] d26bb563a3fa5e186385b66d02cdd24f https://....jpg 04.05.2020, 13:58 ``` * If I clean up unfinished data und restart request. Then sometimes some optimizations work and then the same error again. * The status in wordpress and my.quic.cloud do not match. WP says 94 images requested and my.quic.cloud RequestsStatus show only 0? [my.quic](https://dabbnei.de/my-quic-state.png) [wordpress-image-opt](https://dabbnei.de/wordpress-state.png) * Its unpossible to optimize all images this way…. and if I clean up unfinished, then the counter * Can someone help with this problem? * Last Request: 44m 50s ago and nothing seems to happen - This topic was modified 6 years ago by [mazze5](https://wordpress.org/support/users/mazze5/). - This topic was modified 6 years ago by [mazze5](https://wordpress.org/support/users/mazze5/).

This version works without problems. My pictures were all optimized in 8 minutes. * It seems to be a problem with the new v3 version. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12793528) * Hi, * Do you have any kind of security plugin or access-control plugin ? that’s a typical reason for such error. * Best regards, * Thread Starter [mazze5](https://wordpress.org/support/users/mazze5/) * (@mazze5) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12793549) * Hi, * no, I have not such a plugin. The only pluign for security is at the moment “ WPS Hide Login”, but I think that shouldn’t the problem. I have tested it with I clean WP installation without any plugin and had the same problems. So plugins shouldn’t be the problem at all, I think. * I am wondering as I said in my last comment, because with the older version v2.9 it works. I could yesterday optimize all of my 2500 images, without any error. * Maybe I make a backup and then upgrade the litespeed-plugin to v3 and test it again. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12793557) * Hi, * Yes * d41d8cd98f00b204e9800998ecf8427e * this is md5sum for empty string , that means , something stopped image server from fetching images from your site. * Maybe firewall of some sort. * Please make sure our image server [IPs](https://www.quic.cloud/ips) are whitelisted. * Best regards, * Thread Starter [mazze5](https://wordpress.org/support/users/mazze5/) * (@mazze5) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12793568) * Hi, * yes I have read this. So the frist thing was to ask my hosting provider about this. And they told me, that no IPs are blocked. * So I have to trust this answer… * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12793579) * Hi, * You said you tried on a clean WP without any plugin and still hit this issue, could you please try again , and see you can still reproduce it ? * Also , please ask your provider to check mod_security rule , see if it hits some false-positive alert. * Best regards, * Thread Starter [mazze5](https://wordpress.org/support/users/mazze5/) * (@mazze5) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12795513) * Hi, * ok I will ask my provider. I have tried this morning again, fresh WP Install 5.4.1 with no Plugin, latest Version of LiteSpeed-Cache installed. First 6 images worked, But then request with 93 images, it starts “Images failed to fetch” * Maybe it only happens when more images are requested… * Error on quic: * ``` 07.05.2020, 11:08 Error: Fetched md5 mismatch: [latest] d41d8cd98f00b204e9800998ecf8427e [ori] 863b9a7de59d343fdc8e4adde4df4ad6 https://dabbnei.de/wp-content/uploads/2020/05/lebensmittelpreise-3-768x768.jpg ``` * But after that the next 15 images were pulled without erros. - This reply was modified 6 years ago by [mazze5](https://wordpress.org/support/users/mazze5/). * Thread Starter [mazze5](https://wordpress.org/support/users/mazze5/) * (@mazze5) * [6 years ago](https://wordpress.org/support/topic/imageoptimization-failed-to-fetch/#post-12796831) * But 2 hours ago the last request was started, after the fetch error a few images of the request were optimized and pulled. But after that nothing happend. In the request are still 79 not finished images and after 1 hour of waiting nothing happen. Still 79 images… * Afer a clean up and new request it worked. * I close this issue. Maybe this was a temporarly problem.
