Domain_aliases Only 100 domain aliases allowed

I have a Pro account. I bought wildcard SSL certificate from a third-party yet I still can’t create alias beyond 100.

Yes, you can’t. Wildcard domain is a feature for which you don’t need domain aliases.

Wildcard subdomains can be activated, but there are a few requirements:

  1. The site must be on a Pro or above team.

  2. The DNS must be managed by Netlify OR you need to bring a custom wildcard SSL certificate.

  3. The site should not have any domain aliases or branch subdomains.

  4. The primary domain of the website should be on the same level as the required wildcard domain. For example:

If you need the wildcard to be * where * can be your wildcard subdomain, the primary domain must be (www can be replaced with any string).

  1. You need to configure the DNS for the wildcard subdomain even in case you are using Netlify DNS. You can follow the external DNS configuration for subdomains and add a CNAME entry with * as the hostname or any other value that you want. The value of this DNS entry should be the Netlify site address.

If that sounds like something that would work, please let us know and we’d enable it for your site.
