In my case, it's only one URL inside scrset. I have faced another issue now which is related to cache. **We have faced sometimes 404 errors for webp images with the below config** We have configured an internet-facing Application **load balancer in front of the Nginx server**. **We have added 2 instances** **behind the load balancer with a common Redis cache server** for page speed. pagespeed on; # Needs to exist and be writable by nginx. Use tmpfs for best performance. pagespeed FileCachePath /var/ngx_pagespeed_cache; pagespeed RedisServer "172.31.37.141:6379"; pagespeed RedisDatabaseIndex 3; pagespeed Disallow */Magento/backend/*; pagespeed UrlValuedAttribute source srcset image; pagespeed UrlValuedAttribute source data-srcset image; pagespeed EnableFilters inline_images,sprite_images; pagespeed EnableFilters recompress_images; pagespeed EnableFilters convert_png_to_jpeg; pagespeed EnableFilters convert_jpeg_to_webp; pagespeed EnableFilters strip_image_color_profile; I have to go through issue #1686 but not able to connect all points. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
