Could anyone help me to fix this issue and reason why the Stage gate workflow isgetting suspended.
Thanks,

Check your User Profiles and make sure that the user's domain is correct. We've seen workflows suspend with 401 errors when the User Profile Service syncs with AD and pulls the wrong domain name - for
example if your FQDN is corp.company.com and the user logs in with company\username, UPS might have corp\username instead. Hence a 401 error...
Here is a link that includes the steps to fix this:
