URL structure is different in Apache and NGINX. WHY?????

I have hosted my site on NGINX server and site is working well and no issue detected but one thing is found that is different in apache and NGINX for q2a site.

URL structure is different in NGINX as compared to apache.

URL in Nginx for question page is 

<script src="../../qa-content/jquery-3.3.1.min.js"></script>

<script src="../../qa-content/qa-global.js?1.8.3"></script>

<script src="../../qa-plugin/wysiwyg-editor/ckeditor/ckeditor.js?1.8.3"></script>

But in Apache server for same question pages the url parrent is

<script src="../qa-content/jquery-3.3.1.min.js"></script>

<script src="../qa-content/qa-global.js?1.8.3"></script>

<script src="../qa-theme/SnowFlat/js/snow-core.js?1.8.3"></script>

I don't understand why it is happening. I tried to figure it out but did not get any conclusion on IT

Please Scott kindly make me understand.
