Webp images not loading

Hi there,

Webp images are not loading for all images on my website – only a small number of them.

I have tried the method in the other support thread and the media troubleshooting information

https://wordpress.org/support/topic/litespeed-cache-load-webp-for-firefox/

https://docs.litespeedtech.com/lscache/lscwp/ts-media/

But still can’t get all the webp images to load.

Webp images definitely exist on the server, e.g.

This one is loading on the web page:

I have tired deactiavting webp and plugin and activating several times and checked htaccess to. Is there anything else to try?

Thanks
