Hi,
I installed and configured the Workflow Manager farm for SharePoint 2016 , in one of the Application server .
as per our org policy in App server i disabled TLS 1.0 & 1.1 and enabled only TLS 1.2
After i enable TLS 1.2 below service not started and error in event viewers.

Service Bus Message Broker.

The Microsoft Service Fabric Host Service service terminated unexpectedly. It has done this 6 time(s). The following corrective action will be taken in 5000 milliseconds: Restart the service.

I installed in App Server
Workflow Manger 1.0 Cumulative Update 5 Installed
Service Bus 1.1. with kb 3086798 Installed

Below are the steps i did after disable TLS 1.2
-I leave the WF farm
-when i join the existing farm
i get below error

Error] [1/13/2021 5:04:41 PM]: System.Management.Automation.CmdletInvocationException: The system cannot find the file specified ---> System.ComponentModel.Win32Exception: The system cannot find the file specified

Hi @adilahmed,

To enable TLS protocol version 1.2 on Workflow Manager Windows Server Registery, try as following then compare the result:

1.Disable RC4 by changing the Enabled key value to 0 at below Register Paths:

 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 128/128]
 “Enabled”=dword:00000000
    
 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 40/128]
 “Enabled”=dword:00000000
    
 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 56/128]
 “Enabled”=dword:00000000

2.Open the Register Editor, navigate to the below path, and add a new DOWRS “SchUseStrongCrypto” with 1 value.

 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319

3.Repeat the above steps for each workflow manager server, then restart your server to reflect your register changes.
