Breaking css url after changing hosting

After changing hosting, all urls in css file of my addon are not valid.
It is like in css

background: url(/design/themes/responsive/media/images/addons/myaddon/gears2.png)

and worked fine.
But now on client this url is transforming to next


Can anyone help me with this?

Hosting on VPS Ubuntu and nginx.

do you delete cache folder!!

Yeah, sure. But it didn’t help me. So I changed all addon urls in css files to ‘/images/addons/myaddon/your_image.png’.
