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

url('https://mysite/design/themes/responsive/media/design/themes/responsive/media/images/addons/myaddon/gears2.png')

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’.
