You're encountering a known issue that sometimes affects Power Pages when adding a custom domain with an SSL certificate, particularly when the process gets stuck at the "Create SSL Binding" step. Based on Microsoft's documentation and community reports, here are the most likely causes and best practices to resolve it:
Checklist to Resolve "Create SSL Binding" Stuck Issue
🔹 1. Verify SSL Certificate Requirements
Ensure your .pfx certificate meets all of the following:
- Signed by a trusted certificate authority.
- Exported as a password-protected PFX file.
- Contains a private key (2048 bits or more).
- Includes all intermediate certificates in the chain.
- Uses SHA2 (not SHA1).
- Encrypted with TripleDES (Power Pages does not support AES-256).
- Contains Extended Key Usage for server authentication (
OID = 1.3.6.1.5.5.7.3.1)
.
If any of these are missing, the binding may silently fail.
🔹 2. Check DNS Propagation
Even if the TXT record is validated, the CNAME record must also be fully propagated. Use tools like https://dnschecker.org to confirm that your CNAME is resolving globally.
🔹 3. Try a Different Browser or Clear Cache
Some users have reported that the UI silently fails due to caching or browser issues. Try:
- Using Incognito/Private mode.
- Switching to a different browser (e.g., Edge if using Chrome).
- Clearing cookies and cache.
🔹 4. Use the Classic Admin Center (Fallback)
You mentioned trying the older admin center — this is good. If the new UI fails, the classic experience sometimes works better for SSL binding.
🔹 5. Check for Azure CDN Conflicts
Power Pages uses Azure CDN under the hood. If the certificate is not binding correctly, the CDN might still be serving the default *.azureedge.net certificate . This can happen if:
- The binding was not completed.
- The certificate is not correctly associated with the CDN endpoint.
🔹 6. Wait and Retry
If DNS and certificate are correct, but the UI still fails, it may be a backend propagation delay. Wait 15–30 minutes and try again.
🛠️ If All Else Fails
- Delete and re-add the custom domain and certificate.
- Open a Microsoft support ticket via the Power Platform Admin Center.
