New! TLS 1.2 requirement for Start workflows in Nintex Workflow Cloud action


Applies to: Nintex for SharePoint 2016 and 2013



 



For the farm administrator:





  • Transport Layer Security (TLS) protocol 1.0 and 1.1, which is supported by default in Nintex Workflow for SharePoint 2016 (and 2013), is no longer compatible with the Start workflows with Nintex Workflow Cloud action.


  • TLS1.2 is now required to start workflows with this action. You can opt in for TLS 1.2 even if your application framework doesn't support it.





To use TLS 1.2, follow these steps (all servers):



Using Sharepoint 2013: 



 





  1. Create a text file with a .reg extension and the following contents:

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkv4.0.30319]
    "SchUseStrongCrypto"=dword:00000001
    [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoft.NETFrameworkv4.0.30319]
    "SchUseStrongCrypto"=dword:00000001




  2. Double-click the .reg file install,.


  3. Restart your computer for the change to take effect.




Using Sharepoint 2016: 



 





  1. Create a text file with a .reg extension and the following contents:

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkv2.0.50727]
    "SystemDefaultTlsVersions"=dword:00000001
    [HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoft.NETFrameworkv2.0.50727]
    "SystemDefaultTlsVersions"=dword:00000001




  2. Double-click the .reg file install.


  3. Restart your computer for the change to take effect.




Note: This needs to be done on all servers in the farm.
