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.
Fiddler is a free tool that is good for capturing inbound and outbound web traffic to see what kind of error codes might be returned when the client is making the request to the server. This would at least help you narrow down what might be causing the issue. You may also consider reaching out to Technical Support, as there could be a number of different causes for this behavior.
Hope this helps!
Thank you for posting this to the question to GeoNet. Are you able to provide any other details as to what kind of logins are being used by this Portal Instance? Enterprise logins using SAML? Integrated windows auth? Or Portal built in users. Or is PKI involved with this deployment? As Rachel Sears mentioned, fiddler would show more information as to what is occurring. However, it would require additional configuration. Please ensure that fiddler has been configured to decode encrypted SSL traffic by using this guide Configure Fiddler to decrypt HTTPS traffic | Progress Telerik Fiddler.
