Resource:

  • Static Web App Name: NebulyxWebSite

Resource Group: NebulyxWebSite_group

Region: West Europe

Problem description: Custom domain www.nebulyx.ai is stuck in Validating status for more than 12 hours, despite TXT and CNAME DNS records being configured correctly and visible globally.

Steps taken so far:

Added CNAME record:

Name: www

  Type: CNAME

  
     Value: `xxxxxxx.2.azurestaticapps.net`
```1. Added TXT record for validation:

Name: `asuid.www`

Type: TXT

- Value: `<Token>`
   
   - Verified propagation globally (nslookup, whatsmydns) — records are visible across multiple regions.
   
   Checked with Azure CLI:
   
   ```dockerfile
   az staticwebapp hostname list --name NebulyxWebSite --resource-group NebulyxWebSite_group -o table

Result shows:

  `nebulyx.ai` → Ready

  
     `www.nebulyx.ai` → Validating (ValidationToken = `xxxxxxx`)

     
     Curl to `https://www.nebulyx.ai` resolves to Azure Front Door but returns a generic error page.
```**Expected behavior:** Azure should validate the TXT record, flip domain status to **Ready**, and provision the SSL certificate.

**Actual behavior:** `www.nebulyx.ai` remains stuck in *Validating* despite DNS being correct and resolvable.

**Impact:** Unable to serve traffic over HTTPS from `www.nebulyx.ai`. Root domain (`nebulyx.ai`) is working fine.

**Request:** Please investigate and force validation for `www.nebulyx.ai` so SSL can be provisioned.**Resource:**

    Hi I fixed it by deleting the CNAME, Adding the www TXT, manually - it then validated, then I deleted the TXT and re-added the CNAME - and it worked.

    But thanks for the response, it's much appreciated.
