Hi all,
I'm having below problem in a new VM in which browser access to ArcGIS Portal and ArcGIS Server admin all work but arcgis pro can't add portal and server admin at all. I checked traffic with fiddler and found it keeps connecting with HTTP '80' even though I specified url with HTTPS. Anyone has same experience before and share what's going on in that VM.
We have other VMs and all work fine.
