I am having an issue where I can't sign in to Portal for ArcGIS using ArcGIS Desktop and ArcGIS Pro. I can sign in from the same computers using Mozilla FireFox and Internet Explorer.
It use to work all the time and I'm wondering if my I.T. department made configuration changes to the F5 Load Balancer. I can consume Portal features layers within ArcGIS Pro if they are shared with everyone. I've been troubleshooting this for a week or so and have made no progress. Please provide any feedback.
I can sign in to ArcGIS Online and other Portals that don't use the F5 Load Balancers.
