I was working on ArcGIS Pro 2.1.1 when an error occurred and caused my laptop to restart. Once it restarted and I opened ArcGIS Pro it wanted me to provide login / licensing details again.
Every time I type in my username / password I get the following error :
I have checked the URL and it is correct. I tried the normal www.arcgis.com URL as well as our Organisational URL https://esriza-ps.maps.arcgis.com to no avail. I know it is hitting the correct URL because if I type an incorrect password I do get an error indicating that my username / password is incorrect.
I have removed and reinstalled ArcGIS Pro to no avail.
I also ran Fiddler and no significant issues are detected.
