ArcGIS Earth and Portal

[jirkal]

Anyone ever run into a situation where you can’t connect to your Portal through ArcGIS Earth? It keeps telling me to make sure its running and the url is correct... both of which are true. Can connect via web browser and ArcGIS Pro without issue. Enterprise v10.6 and Earth 10.9

How do you connect to your Portal ? Is it with a SSO or with a user/password ? I have encountered this issue with SSO connections from users who work remotely. Usually, the problem is that the users are not properly connected to the network. Windows security then seems to blocks the connection to Portal through ArcGIS Earth, though it is fine with a web browser. I also encountered errors with older computers that didn't use the TLS 1.2 protocol. For instance, ArcGIS Online blocks TLS 1.1 and earlier.
