Domain Masking Shows a Blank White Screen? Here's Why (and the Real Fix)
If domain forwarding with masking shows visitors a blank white page instead of your site, the cause is almost always X-Frame-Options. Here's the actual mechanism, and the fix that doesn't involve turning masking off.
You turned on forwarding with masking so your domain stays in the address bar, and instead of your site, visitors get a blank white screen. GoDaddy's own support docs describe this as "some websites don't support masking," which is technically true but doesn't tell you why, or what to do about it if turning masking off isn't an option.
What's actually happening
Registrar masking works by wrapping the destination page in an invisible iframe served from your domain. That's the entire mechanism, and it's also exactly what triggers the blank screen.
Most modern websites send a security header called X-Frame-Options (or the newer Content-Security-Policy: frame-ancestors directive) with every response. It tells the browser: "do not render this page inside a frame on another domain." It exists specifically to prevent clickjacking, where an attacker embeds your site in an invisible iframe to trick visitors into clicking something they can't see.
When a browser loads your masked domain, it fetches the destination inside that hidden iframe, sees the header, and refuses to render it, exactly the same protection kicking in. There's no error message a typical visitor would notice. The frame is just empty. Your domain, blank page.
You can confirm this yourself: open your masked domain, open browser DevTools (F12), and check the Console tab. You'll see something like:
Refused to display 'https://yourdestination.com/' in a frame because it
set 'X-Frame-Options' to 'sameorigin'.Why this keeps happening, and isn't rare
X-Frame-Options and frame-ancestors aren't obscure settings; they're a default security best practice, and an increasing number of hosts and platforms ship them automatically: Cloudflare, Vercel, Netlify, Shopify, and most WordPress security plugins all set framing protection out of the box. That means the more modern and secure your destination site is, the more likely masking breaks against it. It isn't a bug in your setup. It's the destination doing exactly what a well-configured site is supposed to do.
That also means there's no reliable fix on your end. Some guides suggest asking the destination site's provider to allow-list your domain for framing, but that requires them to weaken a real security control just to accommodate your registrar's iframe trick, and most providers won't do it.
The fix: stop relying on an iframe
The registrar's own advice, when masking breaks, is to switch to plain forwarding, which solves the white screen but gives up the one thing masking was for: keeping your domain visible.
There's a way to keep your domain in the address bar without an iframe at all. An edge proxy fetches the destination's content server-side, on the edge, and streams the response back under your domain. Nothing is embedded client-side, so there's no frame for X-Frame-Options to block; the header is irrelevant because your visitor's browser never tries to frame anything. It just receives a normal page response from your domain.
RedirectIQ's Edge Proxy works this way. Point your domain's DNS at RedirectIQ, set your origin URL, and every request routes through the edge and back, invisibly, with no iframe and nothing for a destination's security headers to reject.
Edge Proxy is available on paid plans, starting on Hobby at $1/mo. Connecting your domain below starts that plan directly:
