Hi,
I'm trying to add a custom domain to an Azure web app but it's failing even if the DNS dig looks good. I've added plenty of them using this method and this is the only one failing. Any ideas?
The domain I'm trying to add is integrations.connector.reachuc.com
I also tried using Powershell but without success. Both error messages in Azure Portal and Powershell are not very useful.
Hi @Yanis Kross ,
Sorry to hear that you're experiencing this issue. Could you please provide us the error messages you are getting from the portal/Powershell?
Regards,
Ryan
Hi @Ryan Hill
Here's the powershell error
I have to add it as an image because there's a 1000 character limit in comments.
This web app has more than 15 domains associated with it and I didn't have to add "TXT" records for any of them, only CNAMEs where enough. Why is this one different?
Hi @Yanis Kross ,
I wanted to confirm that you were successful in adding the custom domain as I'm seeing listed on your app service.
Regards,
Ryan
@Ryan Hill I wasn't successful going through a cname chain or even a direct cname. I've had to call the customer to add a TXT record and that made us lose flexibility.
It's unmaintainable to have to call a customer to change their dns records when we could use the cname chain (As we did before moving to Azure).
The problem still exists and the error message is not useful but it was fixed with a workaround and that's all I needed.
Thanks for trying to help!
Because there's no real answer to the problem I will try to delete this post, I doubt that it will be useful to anyone.

There is a tutorial to add a custom domain to Web App:
https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain
Hope this helps.
Thanks @Cristian SPIRIDON !
I've added more than 15 domains to this very same web app but this domain is the only one that fails.
I'm inclined to think that a character in the domain name is causing a bad request due to the extra periods or the hyphen in the domain. There's most like some code in the Azure API that returns a bad request in this situation when you have more than two periods.
If the domain doesn't take in the portal as well.. then I think that this is a bug in the API. I'd submit a ticket.
Hi Dave. Thanks for answering.
It doesn't work from the Portal or Powershell. I was able to add other domains with the same amount of periods or hyphens. Where can I submit a ticket for this?
