SP not redirecting to idp and no error being generated at SP side

Hi,

We have integrated our SP with Idp (ping federate) for SSO but somehow the SP is not redirecting to idp and giving up the default login page. Kindly suggest what could be the issue

Also on other hand the export metadata link of SP is working fine but have some doubts related to it as it is showing below, let me know if this is an expected behavior in case of ACS & is this TODO means it is not able to read the ACS from SAML config:-

<md:SingleLogoutService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect” Location=“TODO: URL of SLO service endpoint”/>

<md:SingleLogoutService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=“TODO: URL of SLO service endpoint”/>

<md:AssertionConsumerService Binding=“urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST” Location=“TODO: URL of assertion consumer service endpoint” index=“0” isDefault=“true”/>
