@kritanu_123 It helps the tech team if you can give a link to a product that showing the 404.
If it's a new product that you've just created - it can take upto 72 hours to appear on your store front so patience is key
edited to add - looks like your store hasn't fully indexed yet so it may be a couple of days before things settle down and your products start appearing as a lot of work goes on behind the scenes to get new stores set up properly. Have faith your products will appear eventually
