I have this error when trying to launch OS v9 app. I have no issue launching another app that's on v7.4. 

It is not authentication issue, I can access via BUX. The error occur when I try ClickOnce.

 



This has happened before, these tricks worked last few times, but not this time:

1-Clear Cache: Windows + R -> rundll32 dfshim CleanOnlineAppCache 

2-Delete folder 2.0 from C:\Users\USERNAME\AppData\Roaming\OneStream\Desktop

3-Uninstall latest Microsoft updates.

Anything else I should try? Thank you. 

Below is more error detail:
