Hi it is really weird cause this was the only image that was not processed.
The site doesn’t have a password but it has a firewall against attacks and i couldn’t notice any blocked request.
What I did to solve it was delete the original image and leaving the scaled image only and then restore the original image afterwards.
After that the image was replaced by the one processed by Optimole
I really didn’t get what went wrong.
