When you have the same name of API Endpoints in the same controller then it will give this error.

I just pushed a .NET Core 6.0 WebAPI to Azure AppService. When I access the location I receive
the following error issued when accessing the default URL at https://visionsuitecore.azurewebsites.net/index.html below:
Message: Failed to load API definition.
Fetch error
Not Found https://visionsuitecore.azurewebsites.net/v1/swagger.json
My API works perfectly using localhost and within my code, the swagger.json should be located at
https://visionsuitecore.azurewebsites.net/swagger/v1/swagger.json. Further, if I access the URL directly
I can view the contents of the swagger.json as expected.
Why is this and how can I fix it? Please Advise.

I would suggest you enable diagnostic logging and take look into the application logs or you can also run WebApp down detector in Availability and Performance under Diagnose and solve problems in the portal to identify the cause why the api is failing.
Feel free to reach back to me if you have any further questions.
