This is not an Azure issue, wildcard certs only support one level of subdomain, this is how they have always worked. For the URL listed above you need a *.bbb.mywebsite.com cert.
Second Level Subdomains wildcard domains on Azure don't work ?

Double wildcard custom domains not supported by Azure today? Do I understand correctly?
My certificate was issued for *.mywebsite.com (in Azure), my applications in AKS are: aaa.bbb.mywebsite.com, because there are a lot of them.
I cannot get the certificate to work!
If so, it creates very big problems for me.
