During the initial sign-in to ArcGIS CityEngine without an active portal connection, the application only shows a generic connection error instead of providing the detailed certificate warning and bypass options available when adding a portal later via Manage Portals.

Workaround

Manual Certificate Addition

It is possible to manually add the certificate to the Java Runtime Environment (JRE) trust store shipped with ArcGIS CityEngine:

1. Locate the root certificates file:
2. C:\Program Files\ArcGIS\CityEngine<version>\jre\lib\security\cacerts

The keystore password is:

changeit

1. Use the Java Keytool included with CityEngine:
2. C:\Program Files\ArcGIS\CityEngine<version>\jre\bin\keytool.exe
3. Run the following command:
4. keytool.exe -importcert -trustcacerts -keystore "C:\Program Files\ArcGIS\CityEngine<version>\jre\lib\security\cacerts" -storepass changeit -file path\to\certificate.cer
5. Refer to the official Keytool documentation: https://docs.oracle.com/javase/8/docs/technotes/tools/windows/keytool.html for more information.

In some cases, checking "Always trust this certificate" resolves the issue. However, this workaround may not work in all IT environments due to varying security configurations.
