Unable to add custom domain to Azure static web app

Ayodeji B. Alabi 0

I am having trouble connecting a custom domain to my Azure static web app. The validation for both CNAME & TXT has been taking a long time. Can anyone provide any suggestions on how to resolve this issue?

@Ayodeji B. Alabi Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

Could you please let us know are you adding the root/apex or subdomain as custom domain to static webapps?

Are your using Azure DNS or External provider?

I hope you are following these documented steps to add custom domain ? If not please follow those steps and retry the operation. For subdomain we need to CNAME record and for apex domain you need to add both ALIAS and TXT record.

If you are still facing the issue I would request you to help us with the domain name, static webapp name and issue time stamp (UTC) to check and assist you further on this.

Hello @VenkateshDodda-MSFT

I'm trying to add a subdomain, I tried apex as well it did not work

I'm using an external provider

I've followed the steps in the documentation shared

Custom domain name I'm trying to add is nilehub.nileuniversity.edu.ng the static webapp name is delightful-beach-0cedec90f.4.azurestaticapps.net

I think my apex domain is seen as a subdomain "nileuniversity.edu.ng", I'm guessing this is what is causing the issue.

Thank you kindly.

Ayodeji B. Alabi Thanks for sharing more details on this.

From the backend, we can see that there were two domains attached to the above shared static webapp successfully and also we see that the above shared domain nileuniversity.edu.ng is hosted on whogohost domain provider.

Since you are using external DNS provider, I would suggest you check with your domain provider whether A Name or ALIAS record mapping or CNAME flattering is supported by them or not.

If they don't support CNAME flattering, then you need to configure your DNS in Azure DNS and use A record mapping instead of CNAME record mapping, but this results in performance issues as mentioned here.

Feel free to reach back to me if you have any further questions on this.
