I am adding the sub domain and I have added all the details in my DNS provider panel but when I am loading it showing an error please find my DNS provider screen shot in the attachment

Hey @aartijain9818

Have you added a custom domain to your Netlify site?

No i didn’t added it on netlify I am adding it as a CNAME record

You need to add it as a custom domain to your Netlify site as well as adding the CNAME record otherwise it won’t work.
