Hello,
I have researched this topic quite a bit and have not been able to solve my issue. I am simply wanting read ArcGIS online feature service layers. I thought it might be a proxy issue, but confirmed with IT that the proxy is fine.
I put in my credentials and then click on the ellipses for Feature Service. It will simply look and then time out. I have also tried all the authentication types as well and none of them work.
Is anyone else having this issue?
