We are using Microsoft Azure access control service for SharePoint authentication. we have integrated our SharePoint site with google, facebook and yahoo. Authentication with these sites working fine.

Problem is that when user sign-in using google/yahoo/facebook then after enter credential these site redirect to SharePoint now here is a problem  /_layouts/15/error.aspx page on first attempt.

When user refresh browser it show share point site perfectly. In Return URL, i append /_trust  or  /_trust/default.aspx  but still getting same error.

Please guide what could be an issue and how to fix it.

Thanks

Share fiddler trace  with me

I assume your sharepoint page refresh before the authentication can complete which is causing this issue. MS might say same if you discuss this issue with them.

Try to analyze how much time it takes for you to get authentication token from 3rd party accounts and then from azure
