Azure does not support the .ir domain.

Good news on App service managed certificate. Yes, you heard correctly it became GA now and supports apex domain with a country code top-level domain (ccTLD).

Key Features:

  1. Supports Apex domain.
  2. Auto renewed.
  3. Expired in 6 month.
  4. Auto renew 45 days before expiration.
  5. Automate using ARM template.
  6. App Service Managed Certificate for apex domain will take a bit longer to create than for sub-domain because it uses a different validation method.
  7. Not exportable.

I hope this will help you in securing your environment.

Maybe the tutorial you need is this:

map-a-cname-record

Create a free certificate

I had seen this error before, and solve it by the steps below:

  1. Check the CNAME records. Map a subdomain to the app's default domain name needs two records: CNAME record and TXT record. enter image description here
  2. Make sure you enabled the CNAME record mapping in Azure . enter image description here
  3. Clear the records you don't need, like the CAA records, because wildcard certificatesis not support for creating a free certificate. Take care of the limitations.
  4. It may takes a while for this configuration to take effect.

App Service Managed Certificate is still in Preview, there are some limitations with this (as of today), kindly check them below. It's a private certificate to use if you just need to secure your www custom domain or any non-naked domain in App Service.

The free certificate is issued by DigiCert. For some top-level domains, you must explicitly allow DigiCert as a certificate issuer by creating a CAA domain record with the value: 0 issue digicert.com.

The free certificate comes with the following limitations:

  • Does not support wildcard certificates.
  • Does not support naked domains.
  • Is not exportable.
  • Is not supported on App Service Environment (ASE)
  • Does not support A records. For example, automatic renewal doesn't work with A records.

Kindly see the different between App Service Certificate and App Service Managed Certificate. https://microsoft.github.io/AzureTipsAndTricks/blog/tip259.html
