ArcGIS Pro version 2.3 Patch 2 (2.3.2) running on Window Server 2008
I configured Pro to work offline, but now I want to check my license back in. When I try to uncheck the "Authorize ArcGIS Pro to work offline" box, I get the error in the attached screenshot. Please advise how to get my user license back online. I have no problem uninstalling Pro from this machine, but I'm not sure that would check the license back in.
I'm not sure why the error message is saying: "Portal is no longer accessible". Pro is signed into (see other attached screenshot) the very same Portal it's saying is "no longer accessible".
And yes, I am currently signed into Portal as the same user as when I checked the license out.
