When configuring my wildcard custom domain in an app service, I have en error message saying plainly:
"Attribuer un domaine personnalisé
Impossible d’attribuer le domaine personnalisé *.mydomain.com"
Or in English:
"Configure a Custom Domain
Unable to configure the Custom domain *.mydomain.com"
MS documentation says that is is possible to set a wildcard domain, gives step to achieve it, but in my case it doesn't work. My domain is managed by Azure Domaine App Service. I set the CNAME record and the TXT record correctly, I'm able to configure a custom subdomain such as test.mydomain.com, but when I try *.mydomain.com, I still have this error.
Did someone already manage to do this?
