Hello Dhruv,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that your Custom Domain on APIM is not getting updated.
You can resolve the problem with your custom domain on Azure API Management by carefully handle the causes:
- Incorrect DNS settings can cause issues with domain updates. Check that your DNS records are correctly configured to point to your APIM instance. - https://learn.microsoft.com/en-us/azure/api-management/configure-custom-domain
- If you're using a custom domain with a certificate, make sure the certificate is correctly uploaded and configured. Sometimes, certificates might not refresh automatically.
