Post Salesforce Sandbox refresh, Some how Auth0 connection with portal is not working

Post alesforce Sandbox refresh we are trying to re-authenticate auth0 SSO for our Portals but somehow when we put portal login to browser ,it’s throwing “something went wrong” error.
Can anyone suggest what might be missing in configuration steps .
Note- metadata details match both in SF page potal SSO settings and Auth0 end but still portal link (entity id)if used in browser is not taking us to login page.
Auth0 logs error is “invalid request”

Would appreciate any pointer. Thank you
