@font-your-face don't work when 'Aggregate and compress CSS files' is enabled I added font using @font-your-face module and everything works just fine except when 'Aggregate and compress CSS files' is enabled. When I enable css aggregation and compression, whole website use some default font instead imported font in @font-your-face.

Does anyone have problem like this? Some suggestions how to resolve this?
After your compress the CSS using Aggregate option in Drupal, viewing the source code you'll find that there is an syntax error for @font-face.

Check for your syntax, there would be a break-age in that while aggregation.
