I have recently built a MERN app and hosted the backend with Render and frontend with Netlify. Everything was working until I added custom domain on both sides. Now when I go o www.mydomain.com in the browser, it shows “Cannot GET /” which I assume is the browser rendering my backend. I am wondering how I can get it to render my frontend site in the browser instead.

I set up my custom domain in netlify, and it renders with their subdomain, but when I click the regular domain it just shows “Cannot GET /”
