Body

I created a new account for "rackslide" so I could create rackslide.org.

Everything seems to work BUT for some reason I keep getting the NotServedByPagesError error, so I cannot use HTTPS.

Any help would be greatly appreciated! :) Thanks!

Error:
Both rackslide.org and its alternate name are improperly configured
Domain does not resolve to the GitHub Pages server. For more information, see documentation (NotServedByPagesError).

Hey there!

Good news - the issue isn’t in your repository. The CNAME file (rackslide.org) is correct.

The NotServedByPagesError is happening because rackslide.org currently has no DNS records pointing to GitHub Pages, so GitHub can’t serve the domain or issue HTTPS.

You just need to update your DNS like this:

A   @   185.199.108.153
A   @   185.199.109.153
A   @   185.199.110.153
A   @   185.199.111.153

And for www:

CNAME www rackslide.github.io

Remove any other A/CNAME records for @ or www, wait for DNS propagation (could take up to 24h), then re-add the custom domain in Settings → Pages and enable Enforce HTTPS.

Once the DNS resolves to GitHub’s servers, HTTPS should work automatically.

[chriskewl]

Oddly the A settings are already set up and if you go to http://rackslide.org it goes to the GitHub.io page.

Not sure what else I can do.

[julienborgeon]

That part is actually expected: rackslide.org works over HTTP because the A records are correct.

However, GitHub Pages also checks the alternate domain www.rackslide.org (notice the www) before it can issue HTTPS. Since www isn’t configured yet, GitHub treats the domain setup as incomplete, which causes the NotServedByPagesError.

To fix it, just add this DNS record:

CNAME www rackslide.github.io

Then wait for DNS to propagate, re-add the custom domain in Settings → Pages, and enable Enforce HTTPS. Then HTTPS should work and the error will disappear.

[julienborgeon]

If no further DNS changes are needed, then it’s just DNS propagation (just wait a few hours) and refresh on GitHub’s side.
Fingers crossed!

Thank you so much for the help! The page is now live, now I just need to edit it! :)

Well done!!
Enjoy, then! See you around :)

1.Update DNS Records: Go to your domain provider's settings (e.g., GoDaddy, Namecheap) and add this new record:

Type: CNAME

Name (Host): www

Value (Target): rackslide.github.io (Note: If you are using a different repository, replace this with your-username.github.io).

2.Refresh GitHub Settings:

Wait for about 10-15 minutes after adding the record.

Go to your GitHub Repository Settings > Pages.

Remove your custom domain and click Save.

Type your domain again and click Save.

Check the box that says Enforce HTTPS.
