Static file response is so slow at production

We were using Meteor 1.4.2.3 and angular2 with our meteor project and there were not any problem until now .
After we updated to Meteor 1.4.2.6 and angular2 dependinces to newer versions (2.3.0) we faced a problem with our bundled application that runs at our dedicated server. Local version was okay.

Problem is when we hit the url to access our website from any client. Css files (hostname.com/c00dc6a9a22ea9071caae6a78c30481605fefddf.css?meteor_css_resource=true)

and other static files except main js file was loading so slow (like 2 minutes or more).

The interesting part is when we access to website through https there werent any problem at all.

I tried meteor run --production at the local and also there were not any problem.
But when we build the projects and upload that to server and run at server , this problem happens.
Also when i run bundle at the local machine same problem occurs.

this is the screen shot of network:

as you can see css file is pending till forever
