Metadata Endpoint Url cannot be accessed from the sample code

[PriyaShan16]

Hi,
When trying to retrieve the meta data, I am getting an exception. On trying to access the metadata endpoint url in the browser, I am getting error stating "resource not found". The AADInstance name, tenant and defaultPolicy are updated as per our B2C tenant and it's policy.

Could you guide here to resolve the issue.

Thanks,
Priya
