We are trying to add AD FS as a SAML identity provider using custom policies in Azure Active Directory B2C. We have configured the AD FS server using federation server proxy. We have followed the following links for the setup: https://learn.microsoft.com/en-us/office365/troubleshoot/active-directory/set-up-adfs-for-single-sign-on https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/deployment/best-practices-securing-ad-fs https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/design/when-to-create-a-federation-server-proxy

We have added AD FS server as a SAML identity provider in AD B2C using the following link: https://learn.microsoft.com/en-us/azure/active-directory-b2c/identity-provider-adfs?pivots=b2c-custom-policy

Now when we click on the SAML identity provider we are getting the following error: Unable to resolve the IP address for the metadata endpoint 'My-Domain-Name/FederationMetadata/2007-06/FederationMetadata.xml'

Does anyone have any idea/suggestion to resolve this issue? We have followed all the steps in the reference but still not able to get over this issue.
