To investigate the custom domain binding issue, could you please provide the following details?
- What is the exact error message you receive when trying to bind the custom domain? Please share a screenshot or the complete error text.
- What is the custom domain/hostname you are trying to bind?
- Which Azure App Service/Web App are you trying to bind the domain to? Please provide the app name and region.
- How is the DNS configured for the custom domain? Please share the current CNAME/A record details and the corresponding DNS values.
- Is the custom domain already bound to another Azure App Service or resource?
- When did the issue start, and was the domain previously working successfully with this App Service?
- If possible, please share the exact steps you followed before the error occurred.
Once we have these details, we can investigate the issue further.
