My MERN based website is running, www.only4laugh.com, it's opening fine I can access other pages via clicking on funcards thumbnails, and it shows animation preview in this link (<http://www.only4laugh.com/preview/0/jokes/world_record>). But issue is when I copy paste this same link directly to another tab then it shows error "Cannot GET /preview/0/jokes/world\_record", I am confused why it is working fine on my localhost, I need this to preview of cards with customized images. I am not getting why this is happening due to react route??? or maybe NGNIX based issue..... on node I am just serving app.get("/") to serving index.html.
