Site accelerator fails for about 4% of images

I’m not seeing anything outright to cause this.

Is it always the same images that fail, or are they random?

Hi James,

thanks for your reply.

it happens randomly on a 3-5% of the images.
Also, if you take one that fails and remove the “ssl=1” query, it works.

So I tried to remove it for all of them, but most of the ones that worked with ssl=1 does not without…

If I modify an image that does not work from the backend (like resizing it), so changing its filename, it works.

I had my provider double check and totally remove the firewall just in case (tried with other images, of course, because I know we can’t invalidate the CDN) but everything seems to be ok.

Thanks!

It would be good to rule out any plugin conflicts. Would you be able to temporarily deactivate all of your plugins except for Jetpack? If the issue disappears then reactivate one plugin at a time. Refresh your page each time you reactivate a plugin to see what causes the issue to return.
Let us know how did that go.

Hi, I tried but apparently it’s not a plugin conflict.

To be sure, I even changed the upload folder name to change all the file names but still for some images it fails.

Some times removing some parameters (like ssl=1 or strip=all) makes the image work, but it’s not a solution because it brakes other working images…

Thanks for any help you’d be able to provide!

And these aren’t on pages with a ton of images, right?

The tipical page has 15-20 images, and the website is quite trafficated.

Do you think that programmatically segmenting the activation could help?

Hm, yes is there any improvement with Lazy Images on? https://jetpack.com/support/lazy-images/

Working on that: I’m performing a local optimization of the images, removing some of them from the pages (so each page have less images) and after that I’ll try again not flushing all the cache at the same time.

Will get back to you!
