Custom Domain Setup validation failed

**Describe the bug**
Hi,
I am trying to add a custom domain to my Azure Static Web App, but I keep getting this error message:

`An unknown error has occurred while adding your custom domain. Please try again later.`

It shows the status "success" after the validation, but in the custom domain table is it "Validation failed".

Info: I had previously added this custom domain to a storage account. But I deleted this ressource already, so there might be no conflicts between them about the custom domain.

A clear and concise description of what the bug is.

**To Reproduce**
Steps to reproduce the behavior:
1. Setup the CNAME entry to the according value
2. Test subdomain resolution
3. Go to Static Web App -> Custom domains -> Add -> Custom Domain on other DNS
4. Entered the Domain name -> Click Next
5. Check data -> click Add

**Expected behavior**
Configure and setup the custom domain, so it is reachable.

**Screenshots**
If applicable, add screenshots to help explain your problem.

_Shows "Validated"-Status after adding_

_Shows another status in the custom domain overview_

**Device info (if applicable):**
- OS: Windows 11
- Browser Firefox, Edge

**Additional context**
I found a similar Issue, that was solved in the past: [Issue](https://github.com/Azure/static-web-apps/issues/696)
There was the domain flagged and they unblocked it. Is this here the same Issue?

The Azure generated random domain is below:
`lively-coast-0cd3edd03.5.azurestaticapps.net`
