Have you experienced a connection problem between CityEngine 2019.1 and ArcGis Online?
Hi community,
When I try to login to CityEngine 2019.1 via 'Sign In' (top right), the 'Sign In' link does not allow me to login to my ArcGis Online account, I do not access the Login Password window, nothing is happening.
Where does the problem come from? Have you ever seen that?
I updated de ESRI.lib (File / Manage ESRI.lib)
I have correctly defined my entreprise proxy. For example, I can connect to my ArcGis Online Account trough ArcMap 10.5 and ArcGis PRO.
I have this logs error in CityEngine 2019.1 logs :
eclipse.buildId=unknown
java.version=1.8.0_151

BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=fr_FR
Command-line arguments: -os win32 -ws win32 -arch x86_64 -data @noDefault

In the arcobject-java documentation, I see :
com.esri.arcgis.controls.ControlsAGOLSignonCommand (ControlsAGOLSignonCommand (ArcObjects Java API))
And in the log file, it is : com.esri.agol.commands.signInCommand
SignOn // SignIn
I'm not sure that is the beginning of the solution?! 
Thank you very much for you support.
