Workflow editor not opening

Hi please if you may help about workflow editor error on dynamics 365 for finance and operation on premises PU12.

I am receiving the below email whenever I try to open any workflow

Below is a summary of the errors, details of these errors are listed later in the log.

  • Activation of ax-p.bayan.local/…/Microsoft.Dynamics.AX.Framework.Workflow.WorkflowEditorHost.application resulted in exception. Following failure messages were detected:
  • Downloading ax-p.bayan.local/…/Microsoft.Dynamics.AX.Framework.Workflow.WorkflowEditorHost.application did not succeed.

  • The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

  • The remote certificate is invalid according to the validation procedure.

Many thanks.

Does everything else work or are you getting errors about SSL certificates at other places too?

Which browser are you using?

Hi Martin, everything else works fine, from the Orch server itself it doesn’t give any error , it justs installs the app and nothing happen, I tried from another server to open and got the posted error , am using the default IE for windows server 2016.

Thank you
