CPM installations shows .NET errors on platform upload

Modified on Mon, 11 Mar, 2019 at 10:55 AM


When trying to install CPM v10.7 and above, which now uses REST to upload platforms to the vault, you get a failed message for the upload and the logs show .NET errors


This is caused by the fact that the CPM, by default, only supports TLS 1.0 connections which are now deprecated. Organizations that have TLS 1.0 disabled by a GPO will cause the failure above.

In order to solve the issue, you need to update the registry of the CPM and enable support for TLS 1.1 and TLS 1.2:

Create a DWORD "SchUseStrongCrypto"=dword:00000001

Create a DWORD "SchUseStrongCrypto"=dword:00000001

After adding the keys above, restart the server and run a repair on the CPM installation to complete it.
