See logfile for more information" error when attmpting to connect to feature services through our portal. We are using "SecureAuth - SAML".

My question is, is this likely an FME issue or an issue with our Portal auth? I cant find much that relates to this exact auth method with secure auth.

I am using FME desktop 2018.1. have no issues with authentication to our portal through IE or Chrome browsers.
