Ever since being moved to a new corporate domain, I've not been able to get the required Esri Portal Login to work (http 400). There's a small chance it could be a local IT problem (we have more than our fair share). However, I can sign into the portal directly just fine (ourname.maps.ArcGIS.com). I'm wondering if there's something else I should be checking/fixing.
Here is the (redacted) URL that is causing the error:
https://{ourpage}.maps.arcgis.com/sharing/oauth2/authorize?client_id=2ehad2PpbrGp5utt&response_type=... pc's url}%3A3344%2Fwebappbuilder%2F%3Faction%3Dsignin
Thanks
