Enabling wildcard subdomains


My netlify app name is determined-leakey-ea8996 and i have a pro account.

I have been trying to get wildcard subdomain to work for me using a cname record but always get a Not Found - Request ID: **** error.
I stumbled upon this post and see that the admin could enable it for our account.

Can you please help me here.


We have not configured the feature for that site, so it is no surprise it doesn’t work.

Did one of our staff say we’d done so? It is a feature that requires us to enable it for you after reviewing your config, not one that “just magically works” :slight_smile:

Regardless, I have now enabled the feature and do see it working. You will of course have to configure DNS records appropriately, but this test (I assigned a CDN node as though you had configured DNS using curl’s --resolve flag), shows your content being served for a “random” hostname:

% curl -v https://asdf.myresto.co.uk --resolve asdf.myresto.co.uk:443: -o /dev/null
* Added asdf.myresto.co.uk:443: to DNS cache
* Hostname asdf.myresto.co.uk was found in DNS cache

* Server certificate:
*  subject: CN=*.myresto.co.uk
*  start date: Feb  8 17:35:14 2022 GMT
*  expire date: May  9 17:35:13 2022 GMT
*  subjectAltName: host "asdf.myresto.co.uk" matched cert's "*.myresto.co.uk"
*  issuer: C=US; O=Let's Encrypt; CN=R3
*  SSL certificate verify ok.

> GET / HTTP/2
> Host: asdf.myresto.co.uk
> user-agent: curl/7.79.0

Hello, would like to get this feature enabled for our site.

Site is at: suspicious-babbage-5fa6bd.netlify.app

Also have DNS managed by netlify.

For the purpose of what I’m looking for, imagine my users each have a username and I’d like them to be able to go to username.nftr.name and have my ReactJS app redirect to a specific resource, for example nftr.name/username taking in the subdomain as a wildcard. How is this achievable?

If I had a way of telling netlify DNS to send all *.nftr.name traffic to nftr.name but leave the subdomain wildcard in, I could then just parse the subdomain part and redirect to the resource myself.

No duplicate posts please :slight_smile:
